Question 1996 Chevy Astro Ignition Module

I have a 1996 Chevy Astro Van; 4.3 Vortec; 2-wheel drive. It just died going down the road. This has happened before in a different van and I replaced the ignition module. I bought the module and it was different than the one on the van. The auto parts store said they gave me the only one listed for this van. The part is TOTALLY different. The new one has 4 prongs and a 90 degree plug in. The old one has only 3 prongs and a straight plug in. Any suggestions? Desperately need answers!!! Thanks!

Wrong part. How do you know the ignition module is the problem????

Start with "The Basics" below. Tell us what you find.

Just going by past problem and ASSUMING it is the same since it did the same thing. I figured it was probably the wrong part, but why such a different part? The auto parts store couldn't cross reference the number and even find the old part. Any thoughts? We are 35-40 miles from the auto parts store or I would just run it up there!

You will throw parts at the problem unless you diagnose it in order in a meaningful fashion.

You MUST start with "The Basics" to rule out where the problem might be. You may have a fuel, not a spark problem.

Never assume one is the same as the other. Vehicles can be different as night and day.

It's the wrong part. But no part should be replaced until it is checked and found to be defective. Otherwise all you're doing is wasting time and money by throwing parts at a problem till it's fixed. Take your original module to a qualified professional auto parts store and have it checked. Many stores will check it for free. You also have to make sure that fuel is reaching the plugs. For that use a fuel system pressure tester.
