Anybody know anything about them?

Okay I Had to replace the head gasket on my 97 Disco. Not to bad of a job for the most part. Bashed my fingers loosing the head bolts and got work out tightening the new head bolts. The very back bottom bolts sucked very tight spot to get at.

Now on to my problem. The thing will not start. It will crank, but not start. My dad checked for spark, by using a screwdriver and said it wasnt getting any spark. So I was talking with another car guy this morning and he said that you cannot check for spark by using a screwdriver. he said you have to pull the plug and leave it in the plug wire and then hold it against something like the exhaust manifold and that is the way to check for spark. He said that you could damage the coils by using a screwdriver to check for spark. Is that true???

Also when checking over things we pulled the connection plug that goes from the wireharness to the coil pack. With the key in the on position we show power coming from one of the wires out of 5 (we tested the wires coming out of the wire harness). Is this normal or should we see power coming from more of them?

Anybody have any clues as to what might have gone wrong with this? I know we are mainly Lincoln people on here, but thought maybe somebody might have some insight on what is going wrong.

Are you sure the valve timing is right? is that an OHC motor?

Sorry i can't be of much help. A new head gasket on a 97? how many miles?

 

[apbpetey]

not a OHC motor.

Yeah new head gasket at 129,000 miles. It seems like they either go at 100,000 miles or they last forever. Not a hard job to do at all. Very easy as far as head gasket work goes. I just have no clue why I am not getting spark. I have a feeling it may be the crankshaft sensor.

If it's electronic ignition/fuel injected some type of sensor(s) control the spark and ignition timing. Usually the crank sensor controls ignition timing. There will also be some sort of ignition module.

A $20 investment at AllDataDIY.com may save a lot of headaches.

I got an email from alldata offering 5 years for 30 bucks. i'm set for 5 years on the navigator.

code was DIY4FIVE1 - enter it in the "program code" field.

good for 60 days from december 5th, so it's almost expired.

thanks for the info. I am signing up on alldata tonight.

Appearently the ECM is suppose to receive a signal from the crankshaft sensor inorder for the ECM to send a message to the coil pack.

It looks like the wire going to the Crankshaft sensor got nicked. So now I am not sure what to do. The wire is shielded (inside the outer cover of the wire is 1 white wire, 1 brown wire and stranded wire wrapped around the 2 wires). Don't think I can splice this wire. I might have to buy a wire harness inorder to get this taken care of.

Old temporary way of splicing shielded wire was simply aluminum foil over normal wire splice. Usually the shielding is just for RFI purposes.

Splice away.

I wouldn't worry about it unless you have some wierd noise in the radio or something later on.

Well she is back on the road and running. We spliced the wire and that was the problem. I still might pick-up a spare wire harness just incase something happens down the road.
