Ok been battling this issue for a while now

When the car is operating temp and I shut it off for 5 minutes it'll start up no problem.

However if the car sat for maybe 15-20 mins it will refuse to start or will have a hard time stating up. Most cases extra long crank, sometimes more than one extra long cranks or long crank than it catches misses goes to about 300 rpms stall or it will gain composure and idle fine. sometimes it'll stall twice.

Leave the car for about 2-3 hours or more it starts up first try.

Long story short:
When Hot-
5 Mins =Start

15-20mins = No start

2.5hours- or more = Start​

I changed
the Coolant temp sensor = No change
Cam sensor= thought it worked but today it took 2 cranks on the first start of the day
Crank sensor= first thing I changed (Cant remember if this was the reason why I changed it)

Once the car is started it runs and idles perfectly

This has been going on before AND after chipping the DME

Oh and once it starts it does have a weird smell (gas maybe?)

This may have to do with when I let off the throttle the car stinks but as long as my foot is on the gas there's no smell

Young Ken, suggested a clogged return line and the fuel is just running in to the chambers :dunno:

And before the 1st start of they day my car started like it was missing for a second or 2 then continues fast idling normally

This may sound odd, but have you ever changed your O2 sensor?

Changed fuel filter?

Cleaned ICV?

o2 was changed- CEL went away less than a mile for it

Fuel filter was changed last year

ICV was cleaned last year

TB- cleaned last year

Sparks- last year

Coils are all in the right ohm spec (but spark would cause it to act up all the time no?)

Seafoamed not too long ago


Had no CEL after the o2 was changed but the light went out like 2 weeks ago

I have the exact same problem you are having. I have also changed and clean the same parts as you. The next thing on my list was to change my fuel pump and fpr (fuel pressure regulator). Try checking your fuel pressure, after the car is nice and warm.

nope same thing took 2 tries to start it up

My check engine light bulb doesnt work so i cant tell if it caused a code


but then again OBD1 doesnt car for emissions so it probably wouldnt care.

Car ran the same with or without the gas cap
