I honestly don't remember.
It would run for awhile and then quit just like you described earlier. The problem with obd1 is it isn't specific enough. Like obd2 says misfire cylinder number. where one just says misfire. (or something to that effect) The diagnostics on the car never showed the sensor as bad.
On another thought have you checked your fluids, is there gas in the oil ?
Wish you were closer, I need something to do.

It ran fine for about 10 minutes after we put the new fuel pump in then just went burp. We changed the oil and filter when we started replacing everything else. Hopefully soon we will figure out whats going on. We have no intentions of messing with anything until we hook up a tester to it. All the "could" bes are costing us out the behind.

Just to stay on top of things Jammie, my last post was to hopefully help you in great way. To clarify, if the pinout on your connector is exactly like the 1st diagram, you DO NOT need to purchase a scan tool. You will be able to just bridge terminals 5 and 6 and turn the ignition to on and the Check Engine light will flash you all the codes. If you need help deciphering the flashes just ask.
If your connector is not exactly pinned-out like the 1st diagram, you will have to locate a scantool. Please don't try jumping pins on any other connector because you will fry the ECM :p
GM didn't run a test wire to any other 16-pin connector that I know of for OBD1, and its been so long I cannot remember the color codes or the test terminal on the ECM right off hand. Where there'* a will there'* a way, and if you really absolutely had to, you could get those codes without a scanner, but the steps to located the wires needed is probably beyond the scope of how much energy you want to spend on this car :p
And enough of this silliness about hybrid OBD1/2. OBD1.5? The fact of the matter is that GM just began to roll over their entire lines to OBD2 in the '94 model year. Very few cars rolled off the line for 94 with OBD2. A very simple way to tell is if your computer is in the passenger cabin of the car, it'* OBD1, if its in the engine bay, its OBD2.
When the assembly lines started to run out of 12-pin OBD1 connectors, they just started using the new 16-pin connectors for the OBD1 wiring. Thats all. The problem (most likley), is far too many lower hotshot wannabe super engineers (like me) were involved with something as simple as a change like this. I have seen OBD1 cars with 16-pin connectors wired in no less than 6 different ways. Thank you GM Standards.
I apologize for the long post. I was bored

Find the 16-pin connector under dash, drivers side. JammieM, which pinout do you have? X denotes unused terminals.

I appreciate your posts, but as said in previous posts my car will not flash the service engine light we already tried this. When "Autozone" said the same thing.
I am already looking into my options on getting the scantool that will come in handy if this problem ever happens again,
I sorta have an idea on what might be the problem. But the might be an could bes are costing to much. So my car can sit in the drive way getting some good rest until I get the scantool I need. Then my could bes will be narrowed down an wont cost as much money.
I did however go buy a new gasket for the EGR valve and a new oring for the thing the vacuum hoses connect to. Those are both worn out so we will see. I will post though when I do get the scanner in the mail an hook it all up with my issue on what is was.

Actron CP9110 scantool and accessories
The Actron ScanTool I have is the CP9110 and I use the CP9111 plug-in module with it. That module comes with the OBD1 style cable, but our cars use the OBD2 style cable. I ended up buying a tool with the CP9111 and Generic OBD2 module (sorry, model # is missing on that one!) to get the OBD2 cable. You can probably still get the cable alone from Actron, but I don't know the cost.
You don't need the Generic OBD2 module; it won't work on our cars anyway. Just the OBD2 1.0 cable (that'* how it'* marked), the CP9110 ScanTool and CP9111 plug-in.
