95 5.2 grand cherokee
Working on a 95 5.2 liter grand cherokee turn key fires up then dies right away. Replaced pcm, crank position sensor, asd relay, temperature sensors, oil pressure switch. Don't know what to do next. Any advice out there would be greatly appreciated.

Welcome to the forum.
What is the fuel pressure, measured at the fuel rail? Was the CPS replaced w/ a Mopar part? |
39 psi and the cps is a standard motor products
|
There have been CPS issues w/ non-Mopar parts.
The steady 39 PSI is fine. |
Ok thanks for the info
|
Does it have the 95 factory security? Because it sounds like the security system is disabling ignition. Which lets it fire for about 3-5 seconds then cuts off. They are prone to doing this anytime the battery has been disconnected. It is disabled by putting the key in the driver door and rotating fully 3 times (side to side).
