Default 1994 wolnt start

Well I just got it and found out a lot so far, the guy I bought it from said it had a bent pushrod..it's an over head cam . It had a really bad knocking when I turned it over... turned out being the starter loose. From what I can see it's not running because it has no spark.. the plugs and wires seem to be in pretty good shape, and the ignition fuse is good... havent bought a manual yet so I need some help on this one, where should I look next?

you said you checked the fuses. if you have no spark on all 8 plugs. chances are that both coilpacks did not go bad at the same time. so what is next in line I think it is the ignition module. you should get a multimeter and see where you have power to. I think the ignition modules are about $100

also I am not sure but I wonder if a bad crankshaft positioning sensor can cause a nospark situation I think it can but I am not sure. I think the bad ignition module is more common in these engines. you should check for codes even if the cel is not on. especially if you just got the vehicle

A few more thoughts on my 99 I have a 10A fuse for the pcm, a 30A fuse for the pcm relay and a pcm relay if either the 30A fuse or the relay is removed the engine will crank over but not start. My point being that you should check yours and see that all approriate fuses and relays are ok. I can't remeber if you had fuel or not. That might help ud with the DX is we new

I've got the ignition module pulled out now and im gonna have it checked, I'm going to double check the relays and fuses like you said.


thanks,
Tim

Don't forget if you have a tester you can use it to see that you have power to the ignition module, etc. also do you think you have fuel can you smell any any in the plugs.

well I dont think theres fuel getting to the plugs, just found that out. and the ignition module is good, just had it tested. im not sure where the crankshaft sensor is at, maybe you can provide some insight on that.

thanks,
Tim

did you check/replace the pcm fuse and relay. I think the cps can cause a no spark no fuel scenario but i am not positve. do you have power to the ignition module?

all the fuses in this pic are good, are there any more that are elsewhere that could cause no spark? im not sure wheather or not there is power to the module, how do i check that? there are a few holes where i could put the multimeter. I took my crank sensor off and it didnt look to be damaged... I dont know how it completely disconnects becuase I couldn't find a clip. I switched the two relays in the pic to see if one was bad, and there was still no spark. I'm stumped. I've checked the module,coil pack, crank sensor, plugs and wires, and the relays. thanks a lot for your numerous replys, without them I would be completely lost.

thanks,
Tim

so lets review. the engine will crank over but not start, you have no spark, no fuel, you checked coilpacks, IM, etc. you are now checking crank sensor. so it is safe to say that the pcm is not getting an power/ info to start the vehicle. Do you have an owners manual. the relays in the picture, is one of them the pcm relay. there must be more relays. on some trucks they are under the pcm. I think you should get a manual and confirm where the pcm fuses and relays are.

I just had a thought if you just got the truck and it has never ran for you. maybe the pcm fuse and or relay is not even in the truck. Maybe the previous owner or his enemy removed it on the top of some distribution covers it shows what each slot is for. you should try and find an owners manual also.

yes I have a haynes maual, the previous owner told me that it shut off while he was driving so there has to be a relay in it. I dont see any slots that are supposed to be filled that are not. If my pcm wasnt getting power then would my fuel pump cyle when I turn the key?, would it throw codes out? I'm going to look in the book for a relay that im not seeing

thanks,
Tim

I can see from your picture that the cover of the box is labeled. in the pic you have 2 relays. what are those relays for. I am not positive but i think if your pcm relay comes first and must be activated for the fuel pump relay to work. just to review. you have no spark and no fuel correct. you also have a diode for the pcm somewhere I dont know where and I am not sure what it actually does. well I know what a diode is I just dont know the application for it on this truck

those are the fuel pump and e.e.c. power relays. i switched them and tried for spark, if one was bad then i would get spark but no fuel right? I cant find any relays for the pcm, I cant even find the pcm... it says in the manual its mounted on the firewall.. mine isnt. there is also a diode and I havent checked it yet because I have no idea what it does


thanks,
Tim

it would appear that if you swapped the relays and one is for the pcm you would at least get a spark. A diode is like a check valve for electricity. it only allows the current to go in one direction. I would assume the diode for the pcm trys to prevent current from going back into the pcm and frying it. I think you need to get a multi meter and figure out exactly where you have power to. Do you have power to the eec realy. Do you have power to the pcm relay fuse? etc. the pcm are usually on the upper part of the passsenger side firewall, however i might have seen a picture of one that was on the drivers side fender close to the firewall.
* you should check for codes even if the cel is not on
