Hi from the UK,

The other morning my 87GT failed to start. It was turning over fine but no sparking. I sprayed everything with WD-40 and it started fine. However, I noticed on the way to work this morning there was a slight lag when pressing the gas pedal in second gear.

Are these two related? I will check the ECM codes tonight to see if anything has been flagged.

Do you think it might be the ignition module ?? Or O2 sensor ?? Or something else.

Thanks in advance,

TB

Oh, anyone know why the ACDELCO UK website is no longer available?

You could have a bad engine ground that is affecting your TPS signal or a bad TPS (throttle position sensor).

You need a digital multimeter set to check for continuity. It never hurts to add some extra grounds. Our cars have bad electrical connections after twenty years of use and corrosion. The better the signal we can get to the ECM, the better the car will run, Having good grounds or even extra ones helps to accomplish this. You might also want to make sure that your timing is set correctly.

I had a similar problem, but the car started fine. Mine was caused by two spark plug wires going bad.

Come on Trampboy sort it out!

Start with the simple stuff:

Take a plug or two off and have a look. What condition are they in?

Do a quick paper clip trick on the ALDL for any clues.

Like avengador1 mentioned, attach a (temporary) ground (wouldn't bother removing the old one to start with), can get a new cable from Halfords (when you go in to get those exhaust clamps!!! ). Paul T made a post about an easy ground cable position not long ago with a piccy...might be worth giving him a shout. Take the car for a spin and see if things are improved.

After this I'd go for leads and things, although I don't think this would explain your non-starting episode.

Are you visiting at the weekend? Hopefully the Landy will be done(ish) and RUNNING by Saturday , so should have time to fix yer Rodney D tips.

As for O.C.W (who sell AC Delco parts here in the UK), well perhaps it is linked to their appauling lack of respect for their customers, inconsistency, rudeness and general incompetence (thats been my experience anyway). I hope that someone competent takes their place and continues to sell AC Delco parts without the O.C.W. attitude. If you need parts let me know as I'm gonna place a US order soon.

Cheers
PK
