DII keeps dying/won't start

[S Marks]

'99 DII 150K miles

Wife goes to dinner with friends and cannot get it to start a few hours later. I come in and am able to start it, but only after it turns over for a while. I make a break for the house and it cuts out once (loses all power), starts back up while still in motion, then dies for good a short time later. Tow it home and it does nothing but turns over. Few days later, it starts right up. I have not let it run to temp to see if it will cut out and die again.

I suspected that it was the fuel pump (original), but I have not known fuel pumps to fluctuate between working and not. Could this be the case? Is there a known sensor that might cause this type of behavior that occurs once it reaches temp?

Thanks in advance,
Spencer

CkPS.





(crank position sensor)

Translation: Crank Shaft Position Sensor.

When mine went the truck would start from cold, run till 206 on the scan guage and quit. It wouldn't run again till cool.

To diagnose, take the cover off the CSPS, run till it quits, then squirt the CSPS with cold water or canned air to cool it. Should start back up.

Part is 60$ at autozone, but impossible to find 16 hours into baja.

Thanks for the replies gentlemen. I'll check it out using procedure mentioned.

Had a similar issue a few years ago on my 99 d2. Turned out to be corrosion on the connectors on the underside of the fuse box located under the hood. Replacing the box fixed it (after the stealer threw a bunch of other parts at it).

Best of luck

The crankshaft sensor is the only one that has no 'fall-back' strategy in the ECU, if it dies, you're stuck.

I'd agree with the diagnosis, although there are other possibles, including fuel pump and/or relay. The CKP tends to fail open-circuit. Worth keeping a spare, although they are not cheap: LR # ERR7354. Bosch # 0 261 210 158.
