My car has decided that it no longer wants to spark. Actually, it had sporatically decided it did not want to start on a few occasions in the past, but would always start after sitting for a while (I guess it just wanted to prove that it was the one in control)! This had only happened a few times, and I hadn’t yet found the problem. I also hadn’t "done anything" to the car that would have caused this, I don’t think. However, it now will turn over but will not start - at all. I’ve traced this down to a lack of spark (fuel pump runs fine & injectors are injecting).
After performing the diagnostic tests in the Bentley, everything seemed to check out ok (except for the DME, which the tests do not cover). The coil gets voltage at post 15 when the ignition is on, the ground is grounded, but the Q&D spark plug test (connect ignition wire to spark plug, hold outer electrode against ground, turn key, watch for spark) was a failure. I went ahead and replaced the coil and pulse sensor, but this did not solve the problem. My rather limited automotive knowledge would lead me to believe that a DME failure would be the most likely culprit. Oh, the cap, rotor, and wires are all < 6 months old, passed visual inspection, and showed proper resistences based on tests in Bentley.
So, to test this I was wondering if anyone would happen to have an extra motronic unit they could send my way to see if this solves the problem. If so, we can work out a price. I’d of course pay postage either way. Please let me know - thanks much!
Also, if anyone has any other ideas as to what might be causing this please let me know that as well.
Thanks much in advance.
