need help dailt car died

[mikemounlio]

I was driving down the road and it started to cut out like a lose battery cable. About 3 miles later it shut off but wouldnt come back on. It cranks for days but no spark. I have a new dissy, coil, wires, igniter. rotor is spinning. timing belt is still together. just zero spark.

since i git the car it sometimes would have to be in neutral to start up.

I have volts on the black wire with white strip going into the coil. just nothing comes out of the coil.

How are you checking to see if the Coil is putting out power? Maybe the Plug Wire that goes from the Coil to the Dissy is malfunctioning for some reason? Or just got ahold of a bad coil?

[firebush357]

Also, Have you checked the ground to the Coil? I'm not an expert of these matters just trying to throw out some troubleshooting... It might not even have a ground for all I know.

I have a test light that plugs into the coil. I have coils. one from a working car one that brand new. same with dissy and igniter.

Is this the b6t car?

[mikemounlio]

no its the daily stock auto

[mikemounlio]

It had the weird no start issue sometimes. But dropping down to netural and it would start each time. Also it would not go into reverse unless you went to park 1st.

I have no clue what the issue is right now.

Check inside the coil, where the coil wire plugs into it, for corrosion.

He's got power to the coil and has even swapped out a disty that I sent him from a running car. So would this be a power to the disty issue?

Temporarily jump B+ directly from the battery to the coil positive. If there is no spark then, the coil is probably not being grounded through the ICM.

Another thing that could kill spark would be a continuous ground at the coil negative (ground) side. That could be a short or improper wire connection. Also, a very high resistance in the circuit (such as burned Ignition Switch contacts) will allow voltage to be there but not proper or sufficient current (such as the coil needs). This can cause a low secondary voltage that will not jump a spark tester. A voltage check on a non-operating (open) circuit has limited meaning and mainly shows whether or not voltage is completely missing, not what voltage is during operation.

So what should i check and how to do it?

The guys here are knowledgeable & helpful. Try anything. What counts is finding your problem, not credit, ego, or being first. From my chair, I don't know your knowledge or tools. I can't depend on your spark checker to positively verify the spark issue. Acquire 2 jumper wires w/alligator clips & a remote starter switch or a helper for cranking. Jumper wire gauge should equal or exceed coil wires. (1) Secure the coil wire well, (as was previously suggested), no moving, 1/4"-3/8" from a clean ground, no paint. We want to verify if No Spark exists. Check without bright light or block it out, be sure you can verify. Crank engine. If spark exists, other problems must be pursued. (2) Still No spark: leave coil wire secured. You can bypass half the Ign circuit at a time. Connect a jumper wire with clips from battery positive to coil positive. This bypasses any problem in wiring & Ign Switch up to the coil. Crank & verify spark. Sparking indicates problems with Ign Switch, main fuse link, or wiring. Remove jumper. (3) Still No spark: bypass ground control circuit as follows: Remove all wires from coil negative terminal. Turn on ignition & connect a jumper to coil negative terminal. (Keep wire boot on coil tower & maybe use insulated pliers). Tap jumper end to a good ground and you should be making the coil spark. If spark exists, the coil is not being grounded by the ICM or there is a continuous ground from a short - problem is with wiring or module. Turn off Ignition & remove jumper. (4) Still no spark: connect positive side jumper as before. Connect negative side jumper & tap to ground. Coil is now definitely getting B+ & ground. There should be a good spark. No spark means the coil or coil wire is bad. Remove jumpers. ***This is all just a way that you can verify a spark or isolate the problem area fairly quickly & easily with minimal tools. This not the only way you could approach the problem.

Park safety switch.

I think thats all it might be! any idea where this is and how i can bypass
