'87 900T starts but won't keep running, dies -- long Posted by scott47 [Email] ![]() ![]() |
Here's what happened, I drove approximately 50 miles to work with no problems. Later that day when I was leaving the car would start, get to about 1,200 RPM and die. Thinking it was a fuel problem I replaced the fuel filter and the fuel pump with a known good unit. No luck, I ended up having the car towed home and am still trying to figure this one out.
Resources:
•Townsend Imports - No Start Check 2.2 LH http://townsendimports.com/Web/engine_folder/nostart22.htm
•Bentley guide
Here’s what I’ve found:
•The tank is approximately 3/4 full
•All fuses are good
•The spark plugs (NGK) look to be in good shape and are about 8,000 miles old.
•There is spark at the coil (tested using old plug)
•There is spark from the distributor
•There is voltage present across the injector connectors
•There is power at the Ignition Control Module
•Bypassing the Ignition Amplifier relay doesn’t help
•Continuing to hold the key in the start position doesn’t help.
•If I start the car and push the gas pedal to the floor it will usually continue running at approx 800-1100 RPM until I release the pedal, then it dies immediately.
According to the Townsend Imports instructions since there is voltage across the injector connectors, the ECU and its relays are working as they should and the problem is with the fuel flow/level or the spark.
I have a new cap and rotor but the ones that are on the car now look great.
I’ve started to do the HALL sensor tests from the Bentley guide but haven’t had time to finish them.
I plan on testing another Ignition Control Module from an ’89 900T (if the part numbers are the same).
Are there any other items that I should be looking at or any “tricks” that anyone has to share? Any ideas, thoughts, questions or suggestions will be greatly, greatly appreciated.
Thank you very much,
Scott
