P0202 code, hard start, shaking
THE JEEP BREAKDOWN...
04' Grand Cherokee 4.0 Liter - 122k miles (have owned since 06' w/32k)
First Issue: Hard Start, fuel gauge quit working, I knew we got bad gas sooo....
--New Fuel Pump (fixed gauge, still hard start)
**Did fuel pressure readings...reading fluctuated...erratic***
--New Fuel Filter/Pressure Regulator (redid pressure test, reading steady and within range but still dropping)
--New Injectors (found 2 to be leaking back into cylinders)
Still Hard Starting but since new injectors NOW am getting P0202 Cyl 2 Injector Circuit Malfunction... (ASD relay and all other relays/fuses checked and good)
**Did Continuity test from PCM to injector** Wiring all Good
**Check for power at Injector** Getting Power
**Tested Cam sensor** Cam Good
**Pulled OPD for visual** OPD Good
**Did vacuum gauge reading looking for any leaks** Vacuum within range
**Disconnected exhaust, redid vacuum readings to test for exhaust blockage/clogged CAT** Same Results-Exhaust/Cat good
**Crank sensor in tight spot so hard to test, parts changed it**
--New CPS, no change
**Put in a new PCM, no change.**
**New TPS, no change**
Hooked up NOID Lite, the injector circuit is in fact fine, NOID Lite stays lit...but code still comes on so something is telling the computer the circuit is bad when in fact it is not.
Still Hard Start, may run smooth for few minutes but once in gear jerks a bit and P0202 comes back on.
Anybody got any ideas???
