I have a 1988 Saab 900 2.0 SOHC N/A that I picked up non-running for $700. While trying to diagnose the problem, I noticed a couple lonely connectors in the engine bay. One appears to be two one-wire female connectors just next to the block under the exhaust manifold. The other is, as best described a half-oval connector with a clip tab and two round female sockets, it looks like it comes out of the main harness which is close to the starter. If i remember correctly, one of the colors on the half-oval was orange. Might post a picture of them later if I get the chance. Would these possibly keep the car from running?

I know there are some problems with the ECUs on these not grounding the FPR during cranking. Thinking this might be the problem. Taking pics of the connectors today and jumping 27 and 30 in the fb.
Really hoping the fuel pump just went out on it, posting connector pics later.
A little hard to hear over the power antenna, but had a friend take a closer listen and nothing...
I had this problem on the same year/engine. It would start and run with the fuel pump jumpered.
This. Jumpering the FP in the fusebox will confirm power at the pump.
I'm guessing those connectors are not related to your issue.

The only place that I can recall those two contact grey 'oval' connectors on the C900 is for the radiator fan. Does your car have one radiator fan, or two?
Does your engine have the starter motor under the exhaust manifold, or under the intake manifold? On earlier cars with K-Jet with the starter under the exhaust manifold, there were additional terminals on the starter that run the fuel pump while the engine starter is cranking. It's possible it's a leftover from that.
Do you have a Bentley manual with the wiring diagram?

I believe it has two, but I see what you are saying. The passenger side fan does have a connector that looks very similar, but looks to be a little bigger...
As for the starter, it is under the intake. Would the remnant connectors be causing my fuel pump problems? Or did they bypass that for the later jetronic cars? I do not have a manual but would be very interested in obtaining one. I bet it would help a lot.

I did not hear the pump, even when close to it.
I guess since I'm not hearing it, the best solution would be a fuel pump? I know the paper clip I used is jumpering them because the insulation on it started to come off from the heat.
Much appreciated
