Need help getting the Ty running (update, IT'S ALIVE!!!)

[AUSyTyIN]

So I got all of the parts back together with the tranny on #14, but it won't start. The truck sat for 4 years, and didn't have a fuel filter. Where the filter should be was a rubber hose. Replaced that. The fuel pump primes, and builds pressure when the pump runs, but as soon as the pump shuts off, the pressure bleeds down to zero. When cranking the motor, the injectors are not firing. There is spark. The fuel does burn, and isn't coagulated. Looks and smells fine. The oil is a little dirty, but there is no fuel smell, and it doesn't burn.

Once you stop trying to start the motor (not cranking anymore) the fuel pump runs for ~10 seconds after the key is turned back to the off position, and even when the key is removed. The truck does have a >5 year old Viper alarm that the previous owner never used. The battery never died on him, but it died since it was parked for so long.

So, I'm thinking either the ECM is junk, or it is something with this alarm system, but I'm still confused as to why the pump runs for so long, and why the pressure bleeds off. I pulled the passenger side plugs, and they were black like the truck had been running rich, but the electrode was eaten away like it was running lean (WTF?).

As for the fuel pump... check your oil pressure sensor on that one... I'm having problems with that. Also, I had a similar viper alarm which was causing a phantom start problem.... took me almost two hours to get it all out but solved my problem.

Pressure bleed down.... worn regulator would be my guess.

As for the plugs.... who knows how long they've been in there man :lol:

Come on, they are UR5's. I though those lasted forever.

I was kinda thinking the regulator too.

Other thoughts?

ECM-B fuse good?

On the FP going down after the pump shuts off, sounds like the pump is working but you might want to check the pulsator in the tank. Mine blew the seals and all the fuel would leak back past them, also causing a lean condition. The truck would idle but die if I put any kind of load on the engine, not enough fuel.

I really don't have anything to add as far as suggestions go, but after you get it running, you can test drive it up to Greeley and help me finish putting mine back together. :lol:

and if you get a chance, send me some pics of #14 for the MHST archive. :tup:

I didnt know we had an archive.

Sounds like you have some wierd electrical issues. Maybe. Ild start out by putting a Walbro in with the Racetronix harness. Its not that expensive just to be absolutely sure. Ild toss that Viper alarm in the closet til you get everything else figured out.If your injectors are not firing then how is fuel being burned? FWIW about the plugs, Ive had plugs like tht before, Ild run pig rich in cruise and idle and lean as hell up top. It made my plugs sooty and crumbled the electrodes.

The fuel isn't being burned. The fuel is not coming out of the injectors. The truck does not even try to run



Can I just pull out the alarm without killing the truck?

Nope. I'm the MHST yahoo group admin in Will's absence. I'm trying to get a record going of all the local MHST (Denver/Wyoming/etc) trucks.

It'll be my personal archive until I get enough pictures to make it worth my time to build a gallery. :tup:

The one in my truck was self contained except for 5 or 6 splices, which I just respliced the way they were and taped back up. It had all kinds of crazy relays and stuff attached to it, and was mostly wrapped around the column and up behind the headlight switch.

Most of the stuff I've found is right by the fuse box, with the excetion of the siren being underhood.

For reference, what I found, which included a valet system, viper alarm, vibration sensor on the column and some other box in the console

OMG thats just plain retarded. Get rid of it Austy. Even if its not your problem what a mess it must be. I talked to Abe today he said you can use my ECM if you want to :tup: If it doesnt snow Saturday I may be able to come help you out. I could bring my F***IN TOOLS!!!

Re: Need help getting the Ty running

most alarms (and by the looks of it your viper alarm as well) will tie into the ignition only.. your thick pink and yellow wires near the column... i think those are the colors.

anyways... your bleed down and priming situation are erelevant to your no start condition.

use a mechanical fuel gauge tapped off the rail.. monitor fuel pressue while cranking.. if there is pressure during cranking and running your fuel pump is fine (atleast for now) To check for fuel, crank it over with the coil disconnected.. you will likely smell raw fuel out the tailpipe or you can pull a plug and look to see if there if fuel saturated on the plug. This will tell you if fuel is atleast entering the combustion chamber.

assuming you have fuel, then check to make sure you have spark by grounding the coil wire.. provided you have fuel and spark you should be getting some "pop" out the tailpipe.. To get it fired you may need to adjust the timing, if out of sync..

i would have to think if you have fuel and spark, your fuses are ok as well as your ecu... once it is running, if it does not want to idle smooth or rev up clean, then again check timing, your map sensor, and your chip calibration.

Does the tach jump when you crank it?

Re: Need help getting the Ty running

I did notice a toggle switch, but I messed around with it and it didn't make any difference.

Ghetto sled - I put a mechanical fuel gauge on it, and it read ~50 PSI when cranking, and it bleeds off. I have unplugged the coil and cranked, and there is no fuel smell coming from anywhere (tailpipe, sparkplug holes with the plugs removed, etc.) The truck has spark.

Jimmy - I didn't notice the tach when cranking, but I'll check that and the fuses.
