I have a 1993 f150 5.0 have changed the distributor spark plugs ignition control module ignition switch timing is correct coil is good pulling spout doesn't work and fuel shut off switch is good has spark and fuel running out of ideas to try
check your emmissions system, make sure EGR is not shot. when you say you have spark do you have sparks to all plugs? how did you determine you have fuel? if yo have spark and fuel the only thing missing is compression and air. can u be more specific, whats happening when cranking, is it poping backfiring, nothing at all, was it running good recently, do you have any codes. ?
why did u cchange the distributor? not knowing your mechanical aptitude, my number one suspect would be distributor not in properly (even the best miss)< or 2 a chinese aftermarket that was junk out of the box.. LOTS of mr changs parts no worky good on these old trucks..
Will do nothing just cranks no backfire or nothing even on starting fluid compression is good and only changed distributor because we tested for power coming out of the distributor and had no power coming out of it and yes spark to all plugs and fuel at the fuel rail and in the cylinders
It's a 93 the crankshaft position sensor is the pickup coil in the distributor and I have put a new duralast gold distributor in and compression is good and it doesn't fire at all it doesn't even fire on starting fluid
sometimes ignition wont pop if fuel isnt there, do you hear the fuel pump whirrr when you turn the key to run? open gas cap or have someone help listen or turn key for you. fuel pump fuse... if no whirrr, maybe fuel pump relay. when you try to start it see if your getting voltage to your coil
I would pull the distributor cap and make sure the wires from the signal coil are plugged in good, make sure all connectors are plugged in snugly . it sounds like a timing problem. if your gettng spark, and you have compression, if it is firing at the correct time, it has to run,. are you 100 PERCENT positive the distributor was put in correctly, can you verify . pull number 1 plug and pull valve cover off, bump it till piston gets to tdc, and rotor is pointing to number one plug wire, make sure both valves on number one are closed.
on chevys there is a wire that must be unplugged when u set base timing, then you plug the wire back in, and computer takes over. not sure if Ford uses same system.. its called a bypass ignition system on chevys.
scanner danner has some good vids on you tube abt ignition systems.
We put the number 1 cylinder to tdc and pulled the distributor and put the new one in in the same exact spot it's not a timing issue and it doesn't fire or backfire can I get someone else to answer possibly because at this point I have repeated myself a few times and your still going to conclusions that we have already checked
last reply.. IT CAN STILL BE INSTALLED 180 degrees off if you didnt verify if the cam was on its compression or exhaust stroke, the eng reaches TDC TWICE in a cycle.
how did you verify it was at TDC on the compression stroke? also you cant just put a new distributor in just like the old one was and expect it to be right.. you need a timing light. go see autozone for the rent a tool program..
If you have spark which you say you do at the spark plugs (every one), if you have compression , which you say you do,, (all cylinders, ), and sprayed some starting fluid as you said you did, it has NO CHOICE but to run if it is in correct timing .
Yet you insist you do not have a timing problem because it took you forever to get the distributor back in., listen ive been there, good luck!!!
