Exclamation Cranking, No start

2000 9-3 convertible 2.0 :

Over the summer my Saab would intermittently not start. Engine would crank, but no start. After waiting 20 minutes or so, it would usually start right up. Last week it would not start period.

What I have done so far (after researching myself online):

Replaced the direct ignition cassette,
Replaced the crank position sensor,
Replaced the fuel pump.

Still no start.

I put a code reader on the car and do not get any codes, Im sure whatever codes were stored were wiped when i disconnected the battery to install the DIC.

I am not a mechanic and have no special equipment. But I need my car running and am running out of money and ideas trying to fix this issue.

Can anyone point me in the right direction? What can I do to check possible issues?

Thank you.

Grounds - start there, clean and repair all of them. Check for injector pulse - be sure they are firing when starting - this will rule out or in the fuel/electronics. All fuses check good? Cover the basics too - never forget the basics.

Although you've replaced the fuel pump, take the rubber boot off the inlet to the throttle body, open the throttle body by hand and give a good shot of starting fluid down into the intake manifold then crank. If you still don't get ANY sputter, then you've got no spark.

Another quick way to check for fuel pump operation, is to (with the key OFF!) crack open the banjo bolt on the fuel rail that feeds fuel to the injectors. It'll piss and spray fuel for a minute, but open it up and bleed off ALL pressure. Once its done leaking, tighten it back up, go and crank on the car for a few seconds again. Go back to the banjo and crack it up open again. If fuel squirts / sprays out again, then your pump is working, and again....spark is the issue.

As said above....check all of our grounds and fuses. Most likely NOT a fuel issue, but you never know, and a can of starting fluid is $3.

you know mine has done that too, i did the same as you. I did check pressure it was good (careful its a bitch) i checked grounds and everything has seemed okay. HOWEVER i have jiggeled the key when it was doing a long crank it seemed to work. I also replaced the champions that where in it (they where from i guess 2006 when the guy took the car in) and it seemed to start shortly after a week. so dont know if its the plugs killing it they are ngk bp 7 es or something like that. Napa told me that SAAB changed their numbers for the oem replacement

Does that tach bounce on a T7 car when the CPS is good?

Perhaps the ignition swtich is going bad - but that would create a No Crank No Start symtom...

It will start and then die after a few seconds, We've got spark...

I feel dumb for asking, but where is this located?

When i turn the key to "on", i do hear the fuel pump. I was wondering how to check if the fuel is getting to the throttle body now... Again, I have no special instruments to measure pressure.

Thank you everyone for your suggestions so far.

there is a schrader(?) valve on the fuel rail. if you wear some safety glasses and have a rag, you can (carefully!!!!!) depress the little release in the center and it should spray gas out. if it just dribbles or nothing comes out than you don't have pressure at the fuel rail, fuel is not making it there.

I am sure there is a better/safer way to test but I did this to diagnose my suspected failed fuel pump and sure enough, a only few droplets dribbled out and there was no pressure behind it... yep, fuel pump.

Ok thanks for that. Nothing coming out when i depress that. Fuel pump already replaced. Does that mean the check valve is bad? if so which one...

yes, the fuel filter is dirt cheap and easy to replace. Might be worth it to try that. If no fuel it getting to the rail, something is either blocking the line, or not pumping fuel (bad pump or bad fuse or no power to the pump) right?

I actually know of a 9-3 or ng900 that was abandoned because the mechanics tried "everything" and could not make it start. Then a Saab tech picked it up for nothing and put a new fuel filter in and it fired right up.

I'd look at the top of the tank and make sure that whoever did the fuel pump work, didn't put the feed and return lines bass-ackward when they reinstalled the pump. I forget exactly how they work, but one is the feed, and it only allows fuel out when the car is on its wheels (if it rolls over, a little ball valve closes and stops fuel flow) and the other only allows fuel to dump back into the tank. I think if they reversed them, then you would get no flow at all. Check that before you replace the fuel filter.

A clogged filter will still allow the car to at least run, and they don't clog instantaneously. If your car was running, then it died and you had the fuel pump replaced, start there.

This is a 9k motor, but yours should be similar. Look at the "2.0" on the valve cover, and see the hose, and bolt head just up and to the right of it? About 1:00?? If you loosen that, fuel should spray out if your pump is working properly. If you loosen that and get a trickle, then tighten it back up, try to start the car and loosen it again. If you don't get a PSSSH!! of fuel then you've got pump issues. Maybe not the pump, but definitely something related to what was worked on last.

Thank you everyone. Turns out there is a small clear plastic cap on the bottom of the fuel pump. Should have a "remove before flight" streamer attached to it

I removed the pump, saw the cap and removed it. Car runs like a champ now. Sheesh.

Again. Thanks everyone!

LOL, when I changed the pump in mine in Feb I read an online article that stated that very fact first thing because that guy even forgot, glad you found it out without replacing more parts Hope you didnt have to cut a hole in the floorpan under the rear seat like I did to get to the pump.
