Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
i think your problem is the pick-up coil in the distributer.....it isnt sending a signal to the computer that the engine is turning,,thus,not sending a pulse to the injectors.....if it is the pick-up coil,you may concider replacing the complete distributer with a new rebuilt unit,sense the distributer will need to come out and apart to replace the pick-up.....
yes..i know it is the wrong picture,,but is similer
tell me..with the key on,,do you have battery voltage on the plus side of the coil?
so,,we are loosing either spark or fuel.....
i would doubt us loosing spark,,sense you have the voltage on the pink wire,,,
this would mean we are loosing fuel.....
can you keep it running on starting fluid,or,but spraying gas into the throttle body?
this could be a couple of things
the oil pressure shut of switch,,it may be bad and killing power to the fuel pump..this is located on the drivers side of the distributer
or,the pick-up coil in the distributer..
you may concider the fuel pump relay here..it may be getting power only in the start position..so,,check that also//
ok..when you first turn on the key,,the fuelpump will come on for two seconds,then go off..it wont come on again with the key on,unless the engine is turning....the fuel pump should run all the time when the engine is turning and it has oil pressure......i know you have oil pressure,,but,the switch may be bad,,and not letting power though
the computer knows that the engine is turning from inputs from the ignition module and the pick-up coil
sense the transmission was removed,,and this is when the problem started,,,,,be sure to check the oil pressure shut off switch,,it may have got damage to it when the engine layed back,,when the transmission was removed,,it may have hit the firewall
i agree,,they can be agravating
you and you family have a safe and happy thanksgiving
i know you say the alternator was checked...but,,you need to load test the a\alternator.....even if the alternator is putting out enough volts,,it don't seem to be putting out enough amps,,,,,load test it
do you have a load tester or a volt meter?
we will check a few things
lets try this....
tell me how many volts is on the batter with the engine running...with no lights or anything on
will it stay running if you give it throttle?..do you have anyone to help you,,to keep it running?
make sure you have a good body ground here....perhaps from the negative battery post to the body of the truck......you may not have a good ground
sorry for the delay//
if it has one ffrom the engine to the body,,it should be fine..but,make sure it is cclean and tight
glad you got it
thanks for using justanswer
