Hey guys,
We've had a 2006 IC/CE in the shop since about Christmas that will not run. It had quit on the side of the road, and needed to be towed into the shop.
Oil pressure is good, but it won't pump fuel into the filter bowl. The fuel pump/power steering pump was removed and replaced with new, as well as the feed lines from the tank. Even an ecm from another IC had been switched over, but it didn't help. The teeth on both pump and motor all seem good with no chips.
The bus will crank over and over, but no fuel is being pushed into the fuel filter bowl. Apparently at one point they hooked up shop compressed air and blew it into the tank, and the bus ran for a few seconds. We tried it again this morning and it wouldn't work anymore.
Back when the pump was replaced our mechanic found a kink in one of the hard lines going to the filter head, but that was replaced with new.
Any ideas? I'm not actually working on the bus I'm just relaying info to our mechanics.

| Possible obstruction from something dropped in the tank? Sweat sock, rag? Maybe try blowing air through fuel line back to tank. |
Why yes, the ORIGinal CHARGER is a Fastback |

Thanks for the info guys.
They had the bus running for a few seconds with a "Jerry rigged" electric fuel pump and it ran, but didn't have enough GPM or psi to keep it running.
At one point they thought the teeth on the pump were angled differently than the teeth on the bus. It almost looked like the gear on the pump was on backwards. Would this make any sense. It just seems like the pump is not grabbing the gears to turn. There are no visual signs of any teeth damage on either gears.
I'll mention the check valve to them. |

| Our IC buses of this vintage had a problem with braces or baffles breaking off in the tank and floating under the pickup tube. You may want to pull out the pickup tube through the sender plate and take a whizzer and cut 3/8 inch slots in the bottom of the pick up tube so that if the baffle floats under the bottom of the pick up tube, the suction can't grab onto it. |
