Re: 850 Turbo 1996 PO172

Good news, got another new/used pump and the car started on first time, Yipee! One quick question: the pump that works, the rubber line has a kink, should I try to straighten that out before putting everything back together. It started up with no problem.

Re: 850 Turbo 1996 PO172

Haven't figured out how to bench test fuel pump, but, hooked up a voltage light tester to pump relay, light for 15, no light for 87, does this help to diagnose? I disconnected electrical connection of fuel pump in trunk, put light meter into battery side of connector and saw no light on both termina...

Re: 850 Turbo 1996 PO172

What is the best way(hook-up) to bench test the fuel pump, I ve bench tested starters before, but never a fuel pump, and the presence of gas has me a bit worried. I ve got a normal small battery charger. Better be safe then sorry(burned).

Re: 850 Turbo 1996 PO172

I don't hear anything coming from the pump. After a few tries to start, the battery dies. I am trickle charging battery tonight. Am I missing something simple? Running out of ideas.

Re: 850 Turbo 1996 PO172

Got new(used) fuel pump and installed. No start. Tried to jump relay again and no start. Paper clip was hot, though. No fuel at rail. Do I need to prime something, is it the alternator or starter? Hear no sound from pump, seat is down and cover is off of pump, nothing. Battery charge drops to below ...

Re: 850 Turbo 1996 PO172

Thanks for the reply, I hear nothing in the trunk when key is in position II. Will look into information on pump replacement and start that process.

Re: 850 Turbo 1996 PO172

Put battery charger on this morning and got voltage up to 12.6, will not start, have tried to jump the fuel pump relay, but still no start with full charge, looked at spark plugs and they are light grey/silver color and depressed the valve at end of fuel rail and no fuel comes out. I think I am jump...

Re: 850 Turbo 1996 PO172

The humming noise is coming from the throttle body area and lasts for about 15 seconds and then there is a 'click'.

Re: 850 Turbo 1996 PO172

Put the new regulator on this morning, took off fuel pump relay and tried to jump with paper clip, no start. Checked battery and it read, 11.7. All lights work inside the car and headlights work, tried to jump battery with my truck and it still would not turn over. I am thinking the battery is not g...

Re: 850 Turbo 1996 PO172

Thanks Lee, I will try that test in the morning after putting the fuel pressure regulator back together, should I put the new regulator in or save my money? The regulator seemed like nothing was wrong, the rubber gasket showed no sign of distress. I pulled codes again and the same one came up, P1072...
