'97 Jeep Grand Cherokee ZJ Error Code P0351 problem starting
I've been reporting how great my '97 ZJ is after all the work I've done on her. While my wife was gone for three months I barely needed to go out, especially since my granddaughter was doing the shopping ( she is 27 and has lived with us most of her life). A few weeks ago I went out to start the Jeep and the battery was dead. I live in the Coachella Valley near Palm Pringle California. Since May the weather jumped over 105 degrees during the day and for the last three months each day averages over 115 degrees.
I carry a car jumper and hooked it up as the battery was an Autozone Optima top of the line battery less than a year old. With the charger I was able to start the Jeep. Jump to last week, my wife returned and the Jeep started so I made the 70 mile round trip to the airport in Palm Springs. Made a few stops and outside of a sew stalls, once I got on my way I picked up my wife, the jeep started right up and the battery had plenty of time to recharge. We got home just fine but it's been on my mind to take the jeep out and run around for a while but it's been so hot and humid I put it off until we needed to go out today. The engine cranked but wouldn't start. I had recharged the jump starter I keep in back and even while plugged in it wouldn't turn over. I smelled gas and decided I may have flooded her so I would let her sit for an hour or so.
I went out to try again and at first it cranked but wouldn't start. A few minutes later it stared but even with the gas pedal down she would die. I should add that before my wife left I had the fuel pump replaced as well as some cracked hoses. I was getting a misfire in cylinder 2 code but ultimately I couldn't trigger the check engine light and it seemed to run pretty well. Until today.
A little while ago I got her started but she kept dying. Finely I got her to turn over and run pretty smooth without touching the gas. I revel it a few time but decided against taking her out of the garage this time - still about 110 degrees and I didn't want to risk getting stuck.
I plugged my meter in and did a diagnostic. The only code that appeared was a Coil Problem P0351. I had a lot of work done including head gasket repaires (the heads were warped and not cracked so they were sent out to a machine shop by my mechanic to have them flattened and repaired. All leaks were repaired before I had the fuel pump replaced.
I'm lost as to coil problems. Can anyone help me get to the root of the P0351 error code. I planned to have her towed back to the Mechanic next Tuesday as there is nothing I can do during this holiday weekend and I'm hoping I'm not looking at a costly repair.
Any ideas would be greatly appreciated. Thanks for being here to discuss this problem.
