i have washed motors on all of my vehicles and never had a problem but a couple of days ago i degreased my trucks motor. it started right up and i drove it a few miles to make sure it was dry. i noticed it was smoking a tiny bit so i pulled over and raised the hood. it idled for a while and then died but started right back. i drove it a few more miles until it felt like it was driving normal then put it up for thw night. went back a couple of days later and it wouldnt start. isnt firing. i pulled and cleaned all the plugs. still nothing. i didnt pull the plugs off the distributor but thats next. could i have gotten water in the gas? maybe some heet in the tank would help? all the electronics under the hood are working fine. it just wont fire. i feel dumb but i guess thats how we learn. and suggestions?
the saga continues. i pulled the distributor cap to make sure it was dry under there and it seems to be. i left the cap off to let it dry out just in case. im at a loss now. it sucks but i think im going to have to get a mechanic.. lame
you might want to help the situation... by posting info about the truck and the engine devices..all i can easily gather is you have a 53 chevy trucks with a V8 ..spark??? from the coil.... from the spark plug wire ends also.. fuel???air???compression???
of course. sorry guy.motor is a 79 chevy 350 with a small cam but the issue turns out to be not related to the washing. i have a powerjection 3 throttle body injection system on my motor and the system that shoots the intial gas into the throttle bodies isnt doing that. so ive got no gas. it still smelled like gas when i pulled the air cleaner a week ago but today it didnt and when i looked it was dry. i cycled the fuel pump and got nothing. i put a small amout of gas in the throttle bodies and it fired right up and ran perfect. so i sent the manufature a message asking about what i should do to trouble shoot it. so far i have 1200 miles on the injection system without a problem. i hope this isnt a huge deal.
This seems like a good time for you to get all the ohm values of all the sensors from the manufacturer. I would think they should have a good troubleshooting CD to offer. Be sure to ohm out the harness also. Probably if any terminal to ECM connector is more than 1 ohm you have problems there. I'd keep a record of all your readings to help troubleshoot in the future. Is the manufacturer standing behind their product for you?
I believe the powerjection 111 from Pro Products is computer update capable... does the unit have a laptop computer port? it might give you the diagnostic or error codes from that.
i plugged in to the ecu and i have a bad tps. im replacing it today. hope this takes care of it. when you finally have your truck running tip top reliable and something breaks it scares ya a little.
That's great! nothing is more frustrating than NOT being able to drive your truk!
went to the auto parts store and got the sensor. went home removed the old one and compared it to the new one and it looked broken (the new one). took it back to the parts store where they said it was just made that way. drove back home and installed it and when i tried to start the truck the sensor broke into 5 parts.took it back dumped the broken parts on the counter and said "no..i think its broken". they gave me a nicer made in the u.s.a part at no extra charge. i installed it and the truck hit for just a second then the idle shot waaaay up the it died but left a few lingering flames. i pilled the sensor and realized i hadnt made sure the throttle was in a neutral position when i put the sensor on. the way i had it the sensor held the throttle open. i installed it correctly and it started but not with vigor but the idle was nice. i got in and took off down the road. got half a block when it started surging again. i was pissed. turned around and headed home. took a few deep breaths and popped the hood. i had installed the sensor correctly but neglected to plug it in. yes i am a genius. plugged it in and off i went. everything is working fine now. put about 20 miles on it just tooling around town. my truck smile has returned.
thanks to everyone who jumped in to help. it was cool of you to share your knowledge.
Good job. Did the vendor offer any help or information when you contacted them?
I also had a similar situation with the TPS on my "93 Chevy Silverado 3500. I washed the 6.5 turbo diesel engine down and shortly experienced a hard shifting problem. The engine is older technology and doesn't reference all the sensors to operate but the electronic transmission does. At least the TPS is referenced by the trans according to the trans shop that fixed it. That happened many moons ago now and all has been good but I honestly believe water got into the sensor and faulted the sweeper inside the housing. I keep the water away from it!
yes. the vendor was very helpful. i sent an email over the weekend and didnt get a reply which bugged me so i called that monday morning. the tech on the phone listened to the symptoms and told me flat out that it was the throttle position sensor then told me which sensor to ask for at the parts store. although the product isnt perfect it is in my opinion a good reliable system thats worth the price and the customer service they offer makes it even better.my truck has improved by almost 100% in drive-ability since i installed the powerjection 3 system. the only question i really have for the company is this. when i originally called to order i wanted their multi-port system. the tech talked me out of the more expensive system for the cheaper throttle body? i would still prefer a multi-port but i have very few complaints about this system.
