Cal3thousand Posted October 18, 2010 Author Report Share Posted October 18, 2010 Idono how to check injector pulse without the proper test light but it sounds like you have no fuel going through the injectors. Whatever disables the injectors that's probably it.. You could take the injectors/rail off and see if it makes a mess when you crank! That would be the down and dirty way... Contemplating that move... I think I have a big plastic tub that I can use. :lol: Link to comment Share on other sites More sharing options...
Keaton85 Posted October 18, 2010 Report Share Posted October 18, 2010 Look around online for how to test injector pulse. You could probably do it with a DVM. If you have spark, fuel at the rail, compression then injector pulse is the next step. Link to comment Share on other sites More sharing options...
Reximus Posted October 19, 2010 Report Share Posted October 19, 2010 Look around online for how to test injector pulse. You could probably do it with a DVM. If you have spark, fuel at the rail, compression then injector pulse is the next step. basically all you need for these older cars is a test light. connect the test light to a good ground, turn the key on, then disconnect one of the fuel injector plug, poke the test light at one of the terminal. if the test light lights up, then this isn't the terminal that you're looking for, it's the other one. then once you have found the terminal, then connect the test light to the positive side of the battery. connect the test light to the terminal, have someone help you crank the engine. what you are looking for at the test light is a flash every two revolutions. this is to test the pulse from the computer. test the injector using a digital volt meter, set to read ohms. test across the injector terminals. the resistant should be around 14 ohms. (a full on no start problem should be caused by 1 bad injector, and the chance for all 5 to go bad is very very slim) cheers! Link to comment Share on other sites More sharing options...
Cal3thousand Posted October 28, 2010 Author Report Share Posted October 28, 2010 Update: So I replaced the starter again under warranty and found that the Cam Position Sensor rotor on the camshaft was installed wrong. Fixed that and the car starts again!!! Question: It smokes after 30 seconds of idling (It was dark already, so i couldn't tell the color). Could the turbo be busted when I overheated the first engine? I've checked it and there is no shaft play. Could this smoking just be normal for a while? Can I harm the engine by running it?

AverageVolvo Posted October 28, 2010 Report Share Posted October 28, 2010 Clogged cat? Pcv? Link to comment Share on other sites More sharing options...
Cal3thousand Posted October 28, 2010 Author Report Share Posted October 28, 2010 Clogged cat? Pcv? Cat is perfectly fine. PCV would not smoke like this. I just went out there and started it up again. Same thing, smoke after 20 seconds. Smoked more after a light rev. The smoke smells like normal exhaust and floats and disperses like smoke and not moisture. And the idle is smooth. also some light smoking from the turbo itself, seems to be between the two sides but a bit towards the exhaust side. BTW, the lifters tick like no other, but I'm guessing that will pass. Link to comment Share on other sites More sharing options...
bum2kev Posted October 28, 2010 Report Share Posted October 28, 2010 let it run for 15mins it could be burning off all that extra fuel you put into the system. Link to comment Share on other sites More sharing options...
Cal3thousand Posted October 28, 2010 Author Report Share Posted October 28, 2010 let it run for 15mins it could be burning off all that extra fuel you put into the system. I won't risk any damage to the motor if the thing is leaking oil or water? I guess if the turbo is leaking oil, its getting vaporized in the hot side?

I guess if the turbo is leaking oil, its getting vaporized in the hot side? As long as the water and oil are topped up, you should be fine. If you had a huge water leak, you would see it and the low coolant light would appear once the resevior depleted. I doubt it could burn enough oil to starve the engine. Definately let the car get upto operating temp. Is it blue smoke out the back? Link to comment Share on other sites More sharing options...
mulcy Posted October 28, 2010 Report Share Posted October 28, 2010 Congrats man. Sounds like the hard part is over. Just keep an extra careful eye on the oil and coolant until you figure out what's making it smoke. Depending on how long you've run it, it could just be miscellaneous oil and sealants that are burning off (same thing for the turbo). Link to comment Share on other sites More sharing options...

Definately let the car get upto operating temp. Is it blue smoke out the back? I'll have to see it in sunlight to tell. I will run it to op temp saturday and find out. I just wouldn't want to hydrolock the motor in case it was coolant of some sort in the cylinders. Congrats man. Sounds like the hard part is over.

I will definitely keep an eye out on the fluids. I think the coolant level went down, but I always expect some of that due to air pockets. I'll check the oil tonight and make sure its coolant free. (Since coolant sinks in oil, should I pull the oil drain for a few seconds for a look-see?) Link to comment Share on other sites More sharing options...
SlapShot Posted October 28, 2010 Report Share Posted October 28, 2010 Congrats man. Don't worry too much about smoke and lifter tick. Let it run for awhile in your driveway and it should stop smoking...at least mine did. I literally topped the fluids off and let it run for 30 minutes. If youve only briefly run the motor then Id bet that the oil hasn't gotten everywhere it needs to go (thus the loud lifters) so you might need to add some. You can bleed the coolant system to remove the air pockets or just watch for the level to drop and then add as necessary. Link to comment Share on other sites More sharing options...

Glad to hear that smoking is normal(ish) and will hopefully subside. I'll run it until the fan kicks on tonight and report back immediately. I might post a video of the smoke, but I have a pumpkin to carve tonight for a work contest... Link to comment Share on other sites More sharing options...
Cal3thousand Posted October 31, 2010 Author Report Share Posted October 31, 2010 Update: Ran it again last night up until the fan kicked on. It was still smoking like a 3 foot blunt. This was after driving around the block 7-8 times. It drives normally and gets full vacuum ~19psi at idle. Did not get into boost at all. Its also smoking at the turbo/downpipe area. Some seemed to be coming out of the flexpipe area Here's the plan tomorrow: start it and check the smoke color. If its oil, I have been advised to plug the turbo oil supply and see if the smoke stops. It should be ok, since I'll only let it idle and if the smoking stops, I'll know the oil seal is busted. If it's coolant, I'll let the car warm and do a compression test to rule out headgasket/valve/rings. Thoughts? Link to comment Share on other sites More sharing options...

Thoughts? i would not try to block the oil supply to the turbo. doing that will ruin a otherwise good turbo from oil suffocation. do you get a puff of smoke when you first start it the first time when it's cold? cheers!
