Don't know if you have any where you are, but Autozone parts store rent tools and I'm nearly certain they rent fuel pressure gauges. Ya know, if you don't get a hold of one otherwise.

Clarence is about a half hour from me. Send me a PM if you want to get together & check the fuel pressure. I also have a Delco ignition system that you can have for $15. Try it for a week or two & I'll refund the money if you don't think it helped.

Sounds like a pretty good deal. The ignition comes with all the parts and is a delco type II?



Anyways, after sitting for four hours at work, it took about 4-5 seconds of cranking before it started up. It'* hard to say if the fuel filter affected it very much. I'm still sure it'* a fuel system problem but I'm not one to diagnose a car.

Okay, basically it started the same as the video I posted of the car starting a couple mornings ago. One difference was that I didn't prime the fuel system by putting the key in the on position a few times. I'm thinking of changing the fuel pressure regulator. Can someone tell me where the switch is for the fuel pump so I can relieve the fuel pressure?

Why don't you drive over & we'll see if you need a fuel pressure regulator? We can put on the ignition module while your here.

Personally, I'd take up Ted'* kind offer of a gauge and an ignition. Good price on the ignition, better than I did.

If you want to relieve your pressure though, I'd just un-cap your test fitting on the fuel rail, and *carefully* depress the little valve thingy, like you were letting air out of a tire. There should be a squirt of fuel, and you're done. If you get no squirt of fuel, then that'* just a good sign that your FPR IS bad, since there should be pressure there.

But I'd gauge it, just to be sure, since it can be done for free while you meet a BC member at the same time.

You could even park your cars side-by-side in a parking lot somewhere, or in a park under some trees, and take some beauty shots. Make a real "meet" out of it!
