wifes 99 rodeo wont start after sitting overnight. motor spins, but will not "fire" for about 10-15 minutes. soon as it does fire up, you can turn it off and restart no problem. the motor is brand new, replaced 6,000 miles ago with a factory crate v6 $6,000.00 (thank you mr. isuzu may i have another) only thing i can guess is fuel pump leaking down pressure during the night, but doesnt make sense since it wont prime itself right up.... fuelpump is a dealer only item (go figure it would be anyway else) and is $300.00 (real shocker). Anyone else have this problem before or ideas?


going crazy husband

maybe the fuel pressure regulator? See the FAQ's

I would buy this for the price but maybe it is a faulty fuel relay?

got the POS out of the shop today, found out that 2 grounds for the fuel injection system had worked themselves loose somehow. thus preventing the fuel injectors from firing off when the motor was cold.


$75 service fee from Isuzu......
