#1 - I'm trying to fix a car that is going to the junkyard next week. Am I crazy?

#2 - The car was running fine but has been sitting for the last 2 or 3 weeks.
Has fuel pressure while cranking.
Has spark.
Doesn't have fuel injector pulse, SES light suddenly isn't coming on & fuel pump isn't getting the 2 second prime. I thought the ECM crapped out but decided to check for power. It'* getting 12 volts to the ECM but I don't think any of the grounds are working. Does anyone know where the ECM grounds terninate?

My first thought if you have no injector pulse is to check the ICM or connector. The fact that it has spark tells you the crank sensor is working.

My answers -
#1 - yeah, maybe I'm crazy but I prefer to think of it as curiosity with a major dose of stubbornness.

#2 - I'm afraid I left out the most important part of the story. I decided to switch back to the Magnavox ignition incase anyone here needs a Delco unit. Make sure you reconnect all three grounds when making the swap. The ECM grounds there!

How much better are the Delco coils versus the "stock" and how hard are they to change... if better and not too hard are the answers, how much are you looking for, for them?

Ted, are you saying you left out the grounds and found the problem?

Some members have reported a big improvement with the Delco system. I suspect that they may have had a weak coil in their Magnavox system. When my son & I made the swap we didn't think it made much if any difference. It was my son'* car at the time & I really didn't drive it much after the swap, maybe some others will chime in.

The swap itself is easy to do. Here'* a link to the Techinfo article.

Yep, problem solved. When I pulled the negative battery cable from under the coil mounting bracket the other 2 grounds moved up out of sight. When the car wouldn't start I swiapped back to the Delco system & it still wouldn't fire up. The next morning I traced the ECM grounds back to the engine compartment & put 2 & 2 together.
