Svo starting problem

foxchassisfreak 13.05.2012, 22:52
Car ran fine. It died all the sudden. Fuel pump runs, but the car will just fire and die. Cycle the key, fire and die. Any ideas? It has fuel at the rail

pull codes and report back. possibly TFI or PIP.

Maybe ignition switch? They are a kinda common failure item that act like that. lose fire in the run position but has it in the start pos.

On my Svo, the ignition switch was bad. It would shut off if I barely touched it.

The coil has good fire, it definitely seems like a fuel issue.how do I pull codes? And what is pip? I'm not really savvy on this stuff, I'm a carb guy

are the plugs getting a blue spark? PIP is inside of the distributor. there are 2 connectors under he hood near the top of the drivers strut tower. that is where you can check for codes.

if you suspect a fuel issue, run fuel system diagnostics. you will need a fuel pressure gauge connected to the fuel rail via the schrader valve. as others have mentioned, a faulty ignition switch will cause these cars to do some weird stuff.

Yeah, I'll have to get a pressure tester. It has fuel at the rail but the pressure seems low. How much fuel pressure are these cars supposed to have?

I'll replace the ignition switch just to make sure, it's cheap and easy

39-42 psi with the vacuum line removed from the regulator.

ok, thanks man. I'll give that a shot and see what I get. I'm thinking that the piece of rubber fuel line off the pump, in the tank, might have broken. My turbo coupe did that and acted the same way

Ok, just saw this. I believe the 86 had the intank pump, as opposed to the early ones having the dual in-line. You also might look and see if there is an inline filter possibly blocking it as well?

Yes, correct. This one only has one pump. I'll pop a filter on it too and see if that helps

Get a gauge on that rail, go from there.
