help!! motor quits
Have a 4.2 in a 88yj.
When driving down the road the motor just stops running. Turning the ignition to off and then restarting the motor only way to get it running. Thinking its the ignition module, but the either works or not and resetting the ignition should not have an effect, I'm thinking. If it is the module is this bypassable or am I forced to change the module. This one is for you Mike, I'd would appreciate your help. Just rebuilt the motor and installed got about 275 km before this started. just had all vacuum hoses checked and installed properly. One hose is chaffed pretty good coming from the evaporation canister. -- MATT O, it is excellent to have a giant's strength; but it is tyrannous to use it like a giant. |

Re: help!! motor quits
Check your distributor cap and rotor, plug wires etc, then especially check
your Crank Position Sensor. If this is bad or going bad, once it gets too hot, it will cut the engine off.

Re: help!! motor quits
Crank Position Sensor would be located where?

Re: help!! motor quits
Don't have fuel injection, the 4.2 is carbureted.

Re: help!! motor quits
Hi Matt,
If you have to play with the ignition switch than that's where your problem is, and not in a short, or bad connection, or even the brain box. You may get a few ideas from: http://home.sprynet.com/~dale02/list.htm God Bless America, ßill O|||||||O mailto:-------------------- http://www.----------.com/ happy jeeper wrote: > > Have a 4.2 in a 88yj. > When driving down the road the motor just stops running.
