My 95 grand cherokee wont start after it warms up unless you floor the accelerator. It runs fine always and starts when its cold immediately.
When car is warmed up and turned off for about 10 minutes, it will not start back up. I have to wait for about 30 min before it will start again. It will crank just no start. I have a new starter, cam and crank position sensors. Engine coolant temp sensor good. Vehicle has spark, and fuel pressure but I don’t know exactly how much pressure because I don’t have the right gauge. I hear the fuel pump prime as well and fuel filter is integrated with pump. I bought a new purge solenoid too thinking it might have been excess vapor. No idea where to go from here.
No Start Condition
We have developed a step by step chart for just this occasion. Remember, having fuel pressure great but if your fuel injectors are not firing you are still not getting gas. A quick test would be to try spraying some starting fluid in the air filter to see if it wants to run.
