I just did a motor swap on my 99' 2.2 S-10. I blew the old Motor so i replaced it with one i got a junk yard. everythings hooked up right but it won't get fule. the fule goes all the way up to the injecters but won' come out any of them. i checked all the fuses and there fine so what can be wrong?

Check the injector pulse wire coming from the ECM.

Did you replace it with the same year engine?

Recheck the fuel injector harness for tightness.

Check for fuel pressure... I believe those are CPI injectors, which won't open at all under 55(?) PSI

No, his is a 2.2L, totally different engine.

Are you using the injectors that were on the blown motor? If you're using the ones that were on the salvaged engine, they're probably all clogged up with varnish from sitting so long.

IS there a crank sensor on these motors?

did you reuse fuel managment from blown motor( intake,
injectors, and such)? the other motor was at the junkyard for a reason, reuse what you can from your motor, and clean them before transplant.

We replaced the fule rail and injectors and the truck started right up and ran good as new... thanks everyone for you help
