When doing the timing we made certain that the cam sprocket was at 6 o'clock and that the #1 piston was at TDC, and making sure that the distributor rotor was pointing at the #1 Cylinder direction and of course aligned the cam gear at 12 0'clock so dot for dot was lined up on each sprocket. Then later that was completed and put back together tried to starting time and got zilch so nosotros turned the distributor many positions i between trying to beginning information technology and we got dorsum burn down through out the throttle body simply in order for us to get any blazon of running out of it nosotros had to plow the distributor at 180 degrees out but withal ran like poopoo, and under load it had nothing, with the benefactor being in that position (180 degrees from being pointed at #1 cylinder in order to go it to start but poorly has me stuck) and also all the push rods are pushing out oil, all the lifters are moving so I was ruling out information technology beingness a worn cam, but don't know... Please help need to get this truck sold asap to pay my mortgage Email Report

I allways line the dots (cam at six crank at 12) then turn engine over 360º before dropping in the distributor. in that location is a tan wire/black stripe taped to a wire loom inside the passenger compartment below the glove box/dash on a '95. in one case you become your distributor in right and running,disconnect this wire and ready timing to 0º. reconnect when washed.

That I have to disconnect that wire first, re- stab the the distributor crank the engine (should it run at this betoken) then shut it off and then plus the wire back in? Electronic mail Study

Not getting that, u saying I need to line both cam and crank dots at 12 0'clock? Non pointing at each other? Email Written report

The wire is the wire that goes from ecu to distributor so the ecu can adjust timing. With the engine off all of this is moot, I mean the wires are disconnected from the dist anyway when stabbing and well anyway. When you disconnect the wire the computer looses ability to adjust timing and it should render to goose egg position and this is when you set the motor to zero degrees. Either way, with the wire connected or not the engine should start. if it doesn't so something else is going on, be information technology something not connected correctly or timing to far off. 98 Silverado k1500 4x4 350 Email Report

Since you have the forepart cover dorsum on...remove the #1 spark plug,hold on finger over the hole and have someone crash-land the starter over,when you feel pressure stop and manually plow engine over until the marking on balancer lines up with 0 on the timing scale. you lot can now reinstall the distributor with rotor pointing at #i.

The est wire needs to be unplugged to set your base running timing. and so once running, unplug the est wire and with a timing light set to zero degrees. 98 Silverado k1500 4x4 350 Email Study

OK but practise I nevertheless need to have the wire disconnected at this bespeak (not running) while re-stabbing the dist. and manually crank engine and then marker is lined upwards on the HB at cipher? or wait to unplug the wire after I get it running (which gets me stuck cause I figured with this wire plugged in with me trying to re-stab the dist, line the marks upwardly in one case I commencement information technology the ecu volition fight against me>(unless I unplug that wire first earlier I attempt to start>am I wrong) And then damn fustrated Email Report

Agreed. That wire y'all are talking about is one of the couple wires on the harness that plug into the distributor. And so when stabbing you have to have the wires disconnected to the dist. regardless it would be asunder, merely the betoken is moot considering the wire isn't doing anything with the truck not running. This wire allows the ecu to send a signal to conform timing in the benefactor. Ignition off ecu is off anyhow and even if yous had ignition on and all wires on the distributor while stabbing it even so wouldn't movement the timing plenty to affect anything. 98 Silverado k1500 4x4 350 Electronic mail Report
