No Start

[chriskinzel]

I just replaced the 2 prong coolant sensor and now it won't start. When ii took the sensor out I lost some coolant (about 1/2 gallon) down the valley. The car turns over but will not fire. Did I get something wet that ii shouldn't have? Does it just need to dry?
Thanks in advance

Possibly got coolant on the coils but I would start at ground zero.
Assume nothing.
Check spark (pull one plug and listen for spark)
Check fuel pressure.

Since it is cranking you can rule out the common "no start" culprits.

Im with Dynomite on this. DIS modual may not be unplugged at the modual but might have come unplugged at the other end at the coil. It will crank all day long but wont start. Its a tight spot to get your arm down in to. But I'll bet thats it. It happens to me 50% of the time when I have to lift the plenum.

OK this is not fun anymore. Just pulled the plenum and all wires seem to be plugged in. I checked everything in sight under there, and all lookes OK. still no spark! What am I missing?

Time to review what things you may have done since the last time
it ran ok.
There are still no codes set?
The starting circuits are all stock ?(no bypass of starter circuits)
Just making sure.

Have you had any of the connectors to the DIS off?
Did any of the wires get pinched when the plenum got put back in?
Without having a code set this could get difficult to isolate.
Focusing on the DIS would seem correct.
Find out if it's getting 12v.
You'll absolutely need the factory manual for this.

Thanks for the ideas Scott. The car ran fine with the exception of the low coolant code (I think is was 15) befor I replaced the sensor. I did lose a lot of coolant wile replacing the sensor. No codes, no pinched wires, turns over OK but no spark. I did rinse with water os there would not be antifreeze residue in the valley. I have bypassed the VATS and the cluch safety switch. Like I said, it ran fine into the garage. I am going to try to take all electrical plugs apart and spray the with cleaner tomarrow. If that doesent work I think I will just shoot it and put one of us out of missery.

Check the INJ1 fuse. If a fuel injector power wire gets caught under the plenum the fuse can open and then there won't be any power to the coils.

Best of luck.

Don't feel bad, you are not the only one who had to pull the plenum a couple of extra times. Every owner of these cars should know their way around the top of the engine anyhow.

I fixed a vaccum leak just to find out an hour into the drive that my injectors were crap.

then i fixed those only to find out some of the pcv oil mist was leaking out of the i/h gaskets I replaced during the port work- so I had to do that twice too, once I changed my choice of gasket sealer.

See I told you. I knew thats what it was.

What is the DIS?
