My dad parked his 02 Sonoma after it ran fine. Tried to crank it that night, and it would turn over but refused to crank. Today I checked with a spark tester and we were getting the light on when the plug would fire, but it seemed somewhat dim (maybe just me, can't recall how bright it should be). Checked fuel pump...had good pressure. Chjecked fuel filter and seemed clogged/restrictive. Bought another one, still won't crank. Checked exhaust...no problems there. Crazy thing is while it's turning over, it seems every now and then to 'bog' like something's mechanically holding the crankshaft back.....then releases and bogs again. Even with my Ranger next to it running with jumper cables keeping his battery up. We finally tried cranking it so much that smoke rolled out of the starter motor. My question is.....is it the starter doing all this, or did we maybe burn the starter up due to an underlying problem? We took Serp belt off and checked all pulleys and turned motor over with just the crank being turned and it still bogs. Anyone got any ideas?............it'll be Monday or so before he gets the new starter. I just wonder what it could be if it still won't crank. Thanks.  ?

Pressure is right at 60psi. Strange, everything checks out......yet when it's turning over periodically it stops for a sec, then turns over repeatedly again. I can't figure out what's causing the occassional snag. We removed the serpentine and tried and got the same thing. All other pulleys were like new. Crank and starter going it alone and still something acted like it was trying to stop it. I'm kinda lost on this deal........

I have tried for about 4 weeks to get my 1991 sonoma 2.5 going. I lent it to a friend who ran it out of gas. It 's fuel injected so I was not happy to hear that this happened. I have pulled the distributor changed the ignition module, throttle position sensor, O 2 sensor, fuel injector, checked all fuel lines. The only thing left is the fuel pump which is only 1 year old I just put it in. Can it lose pressure from being run out of gas? I put more than 1/2 a tank in to make sure that was not the problem. And if some one pours gas on the fuel injector it will run long enough to burn the gas they pour on it. Help I am at my wits end. And out of money!!!!!!!!

Mine isn't a fuel problem, lol. I posted before the one about the loss of fuel pressure. Then when I asked for other ideas I ended up under someone else's post...................................... Don't know what kinda problem I got
