Question about Chevrolet Express

2 Answers

Hey 66. I'm feeling my way through this site and I hope this is the right way to reach you for a follow up. Back to the 01 Chev Express 3500 5.7L that will only cold start with gum cutter. The fuel pressure is 60psi with key on but drops to 39-40 while cranking and won't start. Light it off and the pressure runs at 51 at idle. The fuel pump is AC delco, less than a year old. ??????

Hi,
Just check that if your original problem is unsolved - contact Fixya to make sure you are not charged twice. Don't accept unless the information is helpful and leads to a fix.

Back to the Chev -

If the battery is over 3 years old - give it a good charge - and try for a start. Sometimes this is the difference between a go and no-go situation. - Even if it sounds OK - it may not have enough to turn over and start.
I can't remember if this is petrol or diesel. If it's a petrol - check you have spark, If it's a diesel - check that all glowplugs are working.

40 lbs of fuel pressure is quite adequate for operation check for stored trouble codes even if the check engine light is not illuminated, the problem may be a cold start sensor or even a O2 sensor primary bank 1

You'll want to check fuel pressure. They are very sensative and will not start if the pressure is a pound to low. The 5.0 and 5.7 should be 60 to 66 psi
