Hi, think i might can help you, have you done a fuel pressure test if not here what you need to do.

1. Start and run the engine. Verify normal fuel system pressure of 339

kPa +/- 34 kPa (49.2 psi +/- 5 psi).

2. Stop the engine. Verify that the fuel system pressure does not fall below

207 kPa (30 psi) in less than five (5) minutes.

3. If the fuel pressure does not fall below 207 kPa (30 psi) in less than five (5)

minutes, then the long crank time may not be due to the fuel system. Further

diagnosis must be made to the entire engine system.

Hope this helps you, because lack of fuel can cause a missfire and by what you said this is were i would start before spending any more money. If i can help just re post.

Thanks dodge tec

Wher is the ignition control module located in a jeep grand cherokee lorado


6 or 8 cylinder? Either way the computer (ECM) controls the coils. 6 cyl has a 'coil rail' and 8 cyl had individual coils on each cylinder. There are crankshaft and camshaft sensors that tell the ecm when to fire each cylinder

Check engine flashing engine misfire jeep cherokee Engine codes show misfire on 1-4 cylinder check engine light flashing at 75mph AC running


1st, replace your spark plugs(for gasoline engine) or heater plugs (for diesel engines)

if this does not work, have a mechanic check the timing of your engine. Engine timing is checked in the distributor, camshaft, and crankshaft.

1999 jeep cherokee 6 cylinder engine light


1.Plugs
2. Vacuum leak
3. Injector fault
4. High or low fuel pressure.
Thats the list of things to check.
This is a #3 cylinder misfire.
There is also TSB about #3 injector needing added heat protection. This could definitely be the cause. I start at plugs and go from there.
Hope this helps.
Thank you,
Lee
