Id use a gage and check proper fuel pressure. Also check that the pressure will hold for a bit, with everything off. If pressure drops like a rock, you have a pressure leak, somewhere? Id check codes, anyway, Ive had inactive codes point me in the right direction.

I'm sorry forgot to tell you that was already done and with the vacuum hose & the fuel injectors replaced the pressured stayed at 50, before it went from 50 to 20 in like a few minutes but we checked after the hose and injectors were replaced and the pressure stayed at 50. Also when I go to start it if I can tell its gonna be a hard start I stop right away and turn the power on and off 3 times but no codes it says "p done" where my odometer is, so its really getting frustrating and I also got a squeaking noise coming from my passenger side rear tire but stops when I engage the brakes and it comes and goes I noticed that when its damp or wet out when I take it out for the drive my brakes lock really easily with just a little push on the peddle but goes away after a few times, I'm thinking that the squeak could be a bearing I checked the front and they look good but haven't checked the back drums. But back to the starting problem with 2 bad injectors leaking fuel could that mess with the spark plugs? I was just gonna replace the 2 but thought I might as well do all 8.

Flooding can cause a hot restart. After hard cranking, can you pull a spark plug and look at it, is it wet. Gasoline can foul spark plugs. Thats a good thought.

i have the same problem ive replace almost everything .... just replaced all 8 injectors yesturday ..... now today check engine light came on and throwing code misfire on 1 ..... please help !!!!!!!!

Did you have this code before you worked on it? Check fuel--spark-- compression on cylinder #1.
