Need help with 1994 Jeep Laredo problem

[byron_whitesides]

Most of the time, it runs great. However, I do have problems with starting, both hot and cold. Also, it stalls at ide - 70 MPH.

I put a new battery and did a tune-up with a diagnostic. There were not problems detected, that I am aware of.

Could it be a crank sensor?

Any help I can get is much appreciated.

	Crank position sensor A crank sensor is a component used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.

Also, I forgot to mention, sometimes when I am driving at high speed and it "stalls", I pump the accelerator pedal a couple of times and it starts going again.

I am not sure if that helps.

check your fuel filter and it may be your pump....when my jeep had a hard time starting after a week or two my fuel pump when out...but other than that i have really no idea :-D [addsig]

The fuel filter was checked, yesterday, and cited as being in good repair by the mechanic who performed the tune-up.

I checked the fuel pump, in accordance with the manual, both with the ignition in the "on" position and with the car started. Everything seemed to be in order.

I was just hoping someone would think it was the crank sensor, as it seems like a relatively cheap and easy fix, whereas the fuel pump looks to be costly.

Thanks.
