Pull a plug wire off and stick a screw driver in the boot and hold the metal part of it about 1/4" away from any metal ground and crank it and see is spark jumps across the plug gap. let me know
About all you can do is test it for spark AND fuel pressure AT THE TIME OF A NO START. If you test those when it is running it wont do much help. If you think about it, all the engine needs to run is fuel and spark so one of them is failing. At the time of a no start, you might try spraying some starting fluid directly into the throttle body and see if it kicks on that. That right there will tell you if its lacking fuel or spark because if it doesnt even try to start with the starting fluid it must be losing spark and if it DOES start for a moment, you know its fuel related. This is a tough one for me to diagnose online but i will be here to answer any questions you have and hopefully we can get to the bottom of this.
Hi, My name is ***** ***** for the delay.
I will do my best to assist you
lets start from the beginning..
so,you do have a spark on the plug wires?
ok,,is fuel now coming out of the two injectors when you turn the starter?
are you there?
yes,,i have read..
so,you have a spark on the plug wires and fuel is spaying into the throttle body..yet,it doesnt even fire?
has the distributor been removed or anything?
if it is in time,getting fire to the plugs andgetting fuel to the throttle body ,there is no reason for it not to at least fire if it is in time
lets double check the timing
1-remove the #1 plug2-turn the engine slowly until you feel air[compression] come out of that cylinder,get the piston all the way to the top on this stroke.3-align the mark on the crank pulley to 0deg.,,now we have the #1 piston up on the compression stroke.4-install the distributor to where the rotor is pointing to the #1 plug wire terminal inside the cap.the engine should fire here.you want the #1 to fire with the piston up on the compression stroke.
it isnt common for this engine to jump time on the chain,but,i have seen the distributor gear strip out at times
the gear on the distributer may have stripped,,your next step is to check the timing
thats ok,,but we need to know..fact is with spark,fuel and it time,it should fire up
drivers side front
here you go.
i will respond when i am back on line
there is no other way to make sure it is in fact in time,,
you dont need a timing light to make sure the distributor is right with the engine
