Ok, just hopped in the truck to go to lunch and no start. Just starter spinning, no catch or even attempt to start. Replaced the fuel pump this past Tues with new genuine from AB. They sent me two new relays as well, for the fuel pump relay and ecm (but I of course lazed out and just installed the new pump, and put the relays on the shelf). I do not have many tools with me and no volt meter. The ecm and fuel pump relays are clicking, but I have no idea if that means they are good or bad or not. Could the relays be bad, even if they are clicking? The fuel rail is depressurized and with the key in on position, am getting no fuel pressure, so pretty sure it is fuel related. Anything else to check for? Thanks everyone. -Robbie | ||||||

by the way, I did hit the inertia reset button, and locked/unlocked armed/disarmed the alarm a couple of times as well. all same response. | ||||||

Is starter is not turning engine or is engine turning but no catching? Former = time to replace starter. | ||||||

engine/starter is turning, just no fuel (i am pretty sure). hit the schraeder valve on the fuel rail and am getting nothing, except maybe a tiny dribble out of the valve, even with key in on position. doesn't feel like fuel pump is running either. no sounds at all, and i have the access cover off. | ||||||

There is a fuse also for the fuel pump (there is on the RRC)? - check the owner's manual. | ||||||

How about a clogged Fuel Filter? | ||||||
| Robbie Donaldson (Robbie) Senior Member Username: Robbie Post Number: 561 Registered: 02-2002 |
just checked fuses, all good. fuel filter was last changed about 3 years ago, so it definitely needs to be done, but i don't think it would just clog up enough to not start at all? especially since no symptoms of stuttering or hard starts? just called AB to ask their opinion. basically need to get a meter on the pump plug and see if there is juice. if so, then bad pump. guess just have to wait till wife can come get me. | ||||||

Just after you insert the key and turn to the run position (before start position) do you hear the fuel pump run. Should run for 4 or 5 seconds then stop. All this can be heard if you don't turn the key to the start position. | ||||||

not hearing the pump at all. hearing the relays click, but not hearing the pump. pump is even exposed as the carpet is up and the access cover is off. nothing. | ||||||

check your wiring on the new fuel pump! | ||||||
| Joey (Joey4420) Senior Member Username: Joey4420 Post Number: 646 Registered: 04-2003 |
Rob is got a point there, the wiring to the pump is subject to rusting if I recall correctly. | ||||||

ok, was able to run home for some stuff and came back. switched out the two relays, still no start. checked voltage at fuel pump plug, 5-6 volts (correct voltage so i am told). actually heard the fuel pump running this time and had some pressure along the rail, but no start. should the fuel spew out of the schraeder valve on the fuel rail? mine does initially, but then just dribbles, even with the key in on position. checked for spark, have spark, no start. starter is running and even gave it a few taps for good measure, nothing. what else am i missing? do you mean the actual wiring of the pump itself? maybe something came disconnected? i'll pull it and check now. any other ideas? thanks guys. | ||||||

Maybe this will help. ../2/46051.html"#333333"> | Robbie Donaldson (Robbie) Senior Member Username: Robbie Post Number: 564 Registered: 02-2002 |
yep, pretty much followed all of that so far. just checked wiring on new pump. looks good. actually pulled the pump out of the tank, plugged it in, then tried starting. pump ran like it should, still no start. maybe there is a really bad clog in the lines somewhere? i am just not sure what to do next. | ||||

check the pressure at the rail with a guage if that's checking out. then it could be time to start running throught the proceedures in the manual. i had a similar no start issue on my RRC and it turned out to be the ignition amplifier. rd | ||||||

Robbie call me. Send me a mail to the discoweb address to get the number. | ||||||
| Mark (Mrroverman) Member Username: Mrroverman Post Number: 102 Registered: 02-2003 |
same thing happen to me two weeks ago. I open up the gas cap let all pressure out and it started. Someone from Discoweb gave me that advice. | ||||||

With the key on, you will get fuel pressure only enough to pressurize the lines, so it's ok that it sprays then just dribbles, it will only run for two seconds. If your pump is running and pressurizing the line then check for injector pulse while cranking. If you have power at the injectors then your problem lies elsewhere. | ||||||

ok, thanks for the advice so far everyone. going to work on it this afternoon. picked up a fuel gauge so will check pressure at the rail. actually tried the fuel cap thing, no dice. hey Rob, how did you diagnose the ignition amplifier? i'll be giving you a call in a few minutes Kyle, thanks. | ||||||

woohoo, she lives! got it started. turned out to be rotor arm. had an old one I had replaced a couple of years ago, put it on and it fired right up. just followed the test procedures in the manual and led me right to the fix. thanks for everyone's advice and support. | ||||||
| Rob Davison (Nosivad_bor) Dweb Lounge Member Username: Nosivad_bor Post Number: 1714 Registered: 02-2003 |
i followed those same proceedures. Bad Rotor Arm happened on my friends too. Was only a few weeks old. Go Genuine! | ||||||
| Robbie Donaldson (Robbie) Senior Member Username: Robbie Post Number: 567 Registered: 02-2002 |
definitely will be going genuine. last one was one of the beck arney's or something. only lasted about 2 years. one in there now is the original lucas i believe. will order genuine rotor arm and dist cap tomorrow. |
