Why does my 93 Honda Accord run fine and then dies going down the road and will start again and die again?


There is a black fuel relay way up under the top left driver side dash that breaks its main wire solder connections on the circuit board under over-heat conditions. Resolder that relay. Starting fluid will show that you have lost fuel delivery under no start conditions. You can use the breather hose from the valve cover for this test.

Hi, 1997 monte carlo that idles, but cuts out when put in gear, or at times while driving. 3.1 engine. 184,000 mi.


I don't have an answer for you, but I do have a similar or maybe even the same issue with mine. It usually starts up fine, and idles and runs fine when first started, however a few blocks or a few miles down the road it starts to cut out on me, sometimes dying completely... throwing it into neutral and pumping the gas usually will keep it running. This has gone on for a couple of months. When it does die, It normally will restart after sitting for a few minutes. Then a couple of weeks ago it died on me (normally this happens when slowing down and coming to a stop,) and would not restart even after a 1/2 hr, I had to have it towed. I periodically attempted to start it for over a week, it would turn over, but nothing more...then someone suggested that I disconnect the auto start box...It started right up. However, it still continues to cut out when slowing or stopping unless thrown into neutral and pumping the gas. It seems to run better on the open highway, than it does in town with all the slower speed and stop n go. I bought this car used about 6 mos. ago, and considering it's age and the 135K miles on it, I don't want to put any more money into it. I just read there is a recall on this vehicle for the fuel pump and additionally the fuel assembly, I'm not sure if this would be the answer to the whole problem or not.

Hi! Just bought a 99 jeep grand Cherokee, 4.7 V8. The day after I drove it off the lot it stalled as I was braking approaching a stop light. It started right back up but noticed it missing at stop lights...


I Found that the outboard PCM cover screw was shorting out the circuit board.

Short story long: I have a 97 Grand Cherokee 4.0L, 138,000 miles. Several weeks ago, I started to have stalling issues. Hot or cold, dry or wet, first drive of the day or last, it didnt matter. The engine would cut out. It felt like it lost all electricals.
At the time it was showing an ASD relay code and primary coil/ secondary ignition code. Swapped the ASD and A/C relays and replaced the coil and iac valve. Same problem. I didnt have time to look at it, so I had the dealer go through it. After 2 days and $200, they called and said it was the ASD relay, and that they put in a new one, and its all good. Um, ok, maybe I missed something. Im a trusting soul, but lets see if this fixes it. The next day the problem was back. I went back to the dealer and they basically said, We dont know what it could be, good luck with that. Now my wife knows why I dont go to the dealer. By the way, the old relay tested good.
My turn. I cleaned connectors, ohmed out wires and sensors, checked for power and grounds. Everything checked good. By now, its showing ASD, crank sensor, and primary ignition codes. Then, with my wife trying to start it, I wiggled the connectors on the PCM. Every time I wiggled the gray C3 connector just right it would run. When I let go, it would die. So I took the connectors apart and tightened up the crimps (I dont recommend doing this without the proper extractors and crimper). Threw it back together and BAM! Same problem. Well, time to bite the bullet and check for bad solder joints on the PCM board. I took the cover off of the PCM and realized that looking through the potting compound is like looking through Guinness Stout. But, I put it back in and hooked it up. It started stronger than ever, and didnt even think about stalling. Yes! I figured that I finally got the connectors sorted out, so I left it over night to cool down. Got up the next morning and it started right up and wouldnt stall even when wiggling the connectors. So I put the cover back on, put the PCM back in, hooked up the connectors, and BAM! It wouldnt start! That was the point when my wife asked, Hows it going? And I, being the methodical aircraft mechanic that I am, said, what the ----? Thats when my wife turned around and went back into the house. While smoking a pack of cigarettes, I thought, Gee, it runs with the cover off, but not with it on. DUH, wonder what it could be? So I backed out the two screws that hold the cover on and BAM! It started right up. Then, while it was running, I tightened the outboard screw and sure enough, it died. I cut the screws (1/4 long, factory screws are 1/2 long Torx head) with a pair of wire cutters , and shes been running great ever since

I have a 95 s10 and its been sitting alot here lately i drove it the other day and it was hard to start and when it did start it didnt wont to run it is missing and stumbling real bad made it up the road...


If the vehicle has been sitting for a while, you should start by draining the fuel tank, and changing the engine oil. Gasoline does go bad if it is just sitting for a period of time, and will cause the issue you describe. Most likely, your issue is simply bad gasoline.

'93 Grand Cherokee intermittently starts and runs


Hi, I had simmilar problem with my 1993 JGC . I ran out of gas and it would not start until the next day. Then it will start and run until I put the brakes on tho stop and then it will die. It starts right back up. Ended up being the voltage regulator in the ECC/ECM. It is at the mechanics shop right now waiting for the ECC to come in.I will post a follow up.
have Fun,
