Hey everyone,
Im at a loss here. I have a 93 Jeep Grand Cherokee 5.2 L
While driving my Jeep the other day i get a Check engine light that popped on, immediately i noticed a voltage drop on my gauge, and the car began to sputter, bucking and wanting to die in the middle of an intersection. I was about 1 mile from home, and wound up limping it to my driveway (thankfully).
I got the OBD code for a bad TPS sensor. No problem easy fix. I go down to autozone grabbed the new TPS (duralast), and install it without issue. I turn the key in the ignition, the car fired over and died about 1.5 seconds later. I attempted to start it again but the motor just cranks and cranks but wont fire.
I figured its possible i have a bad battery/connections. Get new connections for the terminals and have the battery tested. Those are all good. I attempted to start the car again, same thing. Crank but doesnt fire.
Out of curiosity i take off the new TPS sensor and put back the old one. Last time i tried to start it with the old sensor it started, but just ran like crap. Same thing, car cranks wont turn over.
Checked spark plugs and wires - good
Had replaced cap/rotor etc 1.5 years ago
Checked air filter - good
Checked alternator - good
Hooked the car up and tried to jump it - check
Disconnected battery overnight thinking the computer may need to reset.
Fuel filter - its good
Checked to see if it was getting fuel to the fuel lines - check
At this point i am out of ideas. Has anyone come across something similar, or have an idea of what to do next. I did a search on multiple forums and couldnt find a problem that was exactly like mine. I did see that some people say that the after market TPS sensors are crap. Any ideas or clues would be much appreciated.
(i hope i posted this in the right section, my apologies if not)
