'93 850 Won't Start
Tech,
Well. I replaced the starter, but after sitting for a few months it won't start. It still seems to turn over slowly, but it is faster with the new starter. I am getting fuel pressure. When I disconnect the fuel line and turn on the key the pressure is very good. I am also getting spark however it does not seem very strong. What should I look for electrically, and also could I have an injector problem? There are no blown fuses and no fault codes.

You will need to find a noid light. It is a LED that plugs into the injector plug.
You will have 12volts to the plug with the key on. The pluse is a ground pulse from the computer.

Got a noid light. Put it on the first injector.
When I turn the key to start the car there is a bright flash then a dim blinking. When the key turns off there is another bright flash.
Still no start.

Look on the ignition wires they have a Date stamped on them. It is usually yellow or white.
If the wires are old then most likely the cap and rotor are as well.
If it has been more than 5-10 years change them with a good set.
If the Cam sensor was Bad then no spark at all. Same with the speed sensor.
Power stage maybe.

Cap and Rotor did the trick!! Started right up.
But, always problems. The Power Steering Pump sounds like it's falling apart. Lots of bearing clicks and clacks. I guess I need to buy another part!!.
Unless it's the belt tensioner?????
Thanks for all your help.

Yes the wires are 7 years old.
Fill the power steering fluid.
Listen to where the noise is coming from try to isolate it.
If you canm remove the Drive belts. Alt/steering, ETC.
run it and see if the noise is still there.

I'm leaning towards a pulley. The noise continued this morning, but I decided to drive it anyway. After about 10 miles, I was idling and after a loud squealing sound the engine died. It started right up and the noise was gone. Could a pully have separated binding the belt??
I guess I will remove the belt next and try to see if any of the pulleys are tight or broken.

It doesn't have to be Valvoline brand. It is what my local neighborhood dealership uses.
It might be a bad bearing in an Item.
It could also be a timing belt idler or tensioner pulley.
Try to find Asap.
If it is in the timing belt area with the drive belt (Serpentine belt) off then get fixed ASAP.

WEll the serpentine belt melted today when one of the pully's siezed up. I'll check which one tomorrow. However, there was no more noise, so the timing belt and associated pullys seem ok.
