Not Starting Need Help!!tubbs89 07-14-2005, 12:24 AM Ok, I have a 97 SOHC neon Auto. And I've been having some problems with starting it for like the past 3 months. They supposely fixed it at the dealership. Heres what they did """Ran diagnostics test and they came up with engine misfire, also valve cover gasket and spark plug seals leaking. Relpace Spark plugs, Valve cover gaskets, and spark plug tube seals."""But then a week later it wouldnt start so i took it back and said wtf why is it not running now and they look at it again and said o now its your fuel pump. So when i got the money i did the fixin my self b/c i dont have like 600 to pay the dealership. And then after i did that i was able to drive it around like 2 days. (Durring the time the check engine light came one and i had to checked at autozone and it came up as an EGR malfunction and the dude said that i should fixed it) So once again i had to waite till i get some cash and then i went down to NAPA auto parts (b/c i heard from some friends that i knew they said autozone is crap and cheap) and bought a new EGR Valve. Now i can drive it around again 2 days and it died again. So can anyone out there help me? New parts Fuel pump, EGR valve, and all what the dealership did. maykelcj 07-14-2005, 06:02 AM .... das2123 07-14-2005, 08:51 AM During the time the check engine light came one and i had to checked at autozone and it came up as an EGR malfunction and the dude said that i should fixed itWhen you replaced the EGR valve, did you also replace the solenoid with it? I think the EGR valve is actually cheaper from the dealer than NAPA or autozone. Will it crank with a jump? tubbs89 07-14-2005, 03:17 PM I replaced the whole EGR Thing the metal object (that mounts on your engine) that came with it and the plastic circle thing that goes on your stock airbox. When i went to go and jump it it would not start it would turn over just not start. So i looked at the fuel rail and took that cap off and to de-pressured it but im not geting any fuel to come out and i dont think i have any air pressure in it either. theres no fuel pressure i belive am i right? or now what do i do??

You need to check the fuel pressure with a gauge. If you do not have any fuel pressure then it sounds like you got a bad fule pump. tubbs89 07-18-2005, 01:41 PM Is there any way of adding some fuel pressure or is it just a bad fuel pump then... das2123 07-18-2005, 02:01 PM Is there any way of adding some fuel pressure or is it just a bad fuel pump then...Have you checked the fuel pump relay and/or fuse? tubbs89 07-18-2005, 03:36 PM the fuse is good im checking the relay later today tubbs89 07-18-2005, 04:47 PM ok i just went a bought 2 brand new relays for the auto shut down and the fule pump it self and it still wont start.. :( das2123 07-18-2005, 05:07 PM Is there any way of adding some fuel pressure or is it just a bad fuel pump then...You said you replaced the fuel pump correct? What about the fuel filter? Can you hear the pump priming up when you turn the key to the ACC mode? Try that a few times to build up your fuel pressure, before attempting to start the car. After that, looks like your injectors could be going out on you. Just another thought, will it start with a jump? tubbs89 07-18-2005, 06:04 PM It says in the haynes manual that on the 96 and up models that you dont need to replace the fuel filter it is a pice that is attached to the fuel pump and when i replace the fuel pump it looked like i replaced that too. When the car does start you can tell because when you do put it in the acc mode you can hear the pump working and i also the fuel gague thats is in the instrument cluster works. And when it doesnt start that gague doesnt work at all. And i dont have any pressure. Um about the jump i tryed it about a day or too ago (and it didnt start)But since i replaced the relays, i might try it tommaro to see if it will take the jump. It did start today it ran for about 10 sec just idleing then it die. palindromelol 07-19-2005, 11:12 AM I've been following this thread and this does not sound like a fuel delivery issue to me. Why the focus on the fuel system? das2123 07-19-2005, 11:23 AM Why the focus on the fuel system? When i went to go and jump it it would not start it would turn over just not start. So i looked at the fuel rail and took that cap off and to de-pressured it but im not geting any fuel to come outThat's why, you have any thoughts? das2123 07-19-2005, 11:38 AM ok i just went a bought 2 brand new relays for the auto shut down and the fule pump it self and it still wont start.. :(What about the starter relay? Some other thoughts, are the camshaft and crankshaft position sensors. palindromelol 07-19-2005, 12:03 PM Fuel delivery is one thing, fuel pump control, is another. The lack of fluid in the gas line appears to be an electrical issue. As an electrical issue, the fuel pump control, kills the entire fuel system. If it were clogs, I would think that having all 4 injectors clogged simultaneously would be a low odds unlikey bet. If there was 2 or 3 cylinders firing I would reason a fuel delivery issue in the rail. Since all don't work the fault is likely in control of the fuel pump activation. Mr/Mrs Tubbs89, I figure that you have a elevated level of frustration with this problem. It sounds to me that you have established that fluid will conduct from the tank to the fuel rail. Is this true? What is at issue is why the pump won't come on when you want it needs to come on. Is that true? I read that it comes on sometimes but then stops. The fuel guage also dies. Is that correct? tubbs89 07-19-2005, 02:23 PM yea everything is correct. when the fuel gague dides thats when the pump doesnt even come on at all. I can tell when the car will start when i put the key in acc mode i will get a fuel gague saying i have 3/4 of a tank left, and i can hear the pump kick in and making sure that everything has pressure, and the car will start, then it will die after 10 secs of idleing. So more that likely im geting fuel to the fuel rail when i get a reading on the fuel gague,then i try to start it again and the fuel gauge doesnt work at all saying that i have no fuel and i go to fire it and all it does is turn over i dont even here the pump kick in at all or nothing. then i go to remove the fuel line from the fuel rail and i get gas to come out of the line. palindromelol 07-19-2005, 03:31 PM Ok here is the way I see it based on what I have read. 1)The relay is working but may not be instructed to close 2) If the relay closes, the current may not be getting to the pump module. the pump module powers the fuel gage as well as the pump. A plain brown wire from the PCM supplies ground to the control side of the relay in the PDC. A light green with blue stripe wire supplies the power to this same relay. This wire is also connected to 1) Torque converter clutch solenoid 2)Evap/purge solenoid 3) Vap Can Leak detector 4) egr solenoid You may have a short in any one of these devices but unlikely because you'd be getting additional codes. More likely no power at the pump in the supply side. Can you place a volt meter on the wire that supplies the pump and confirm the pump is getting juice? No juice.. no gage , no pump, no flow, no pressue, no start. I think you are looking for a crappy connection intermitant partially failed conductor. A couple of aligator clips, two sewing needles and a volt meter. When you have a fault, just probe the wires through the insulation and confirm volts. Silicone over the pinholes when you are done. Careful around the fuel tank.... sparks are bad. Interesting note. The wires in the pump modual are immersed in gasoline. The gas is an effective insulator. 99 Neon R/T 07-23-2005, 04:46 PM Check the ground wire in the trunk on the driver side it is under the carpet with 1 or 2 more wires.If it is loose then you will get no signal to the gauge and the pump wont kick on.Good luck vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
