TSB 03-21-32 HARD START/LONG CRANK - VEHICLES EQUIPPED WITH AFTERMARKET MODIFICATIONS AND 7.3L DIESEL ENGINE Publication Date: October 7, 2003 FORD: 1997-1999 ECONOLINE Article 98-26-9 is being republished in its entirety as part of a consolidated 7.3L diagnostic aid booklet. ISSUE: Some vehicles equipped with aftermarket modifications may exhibit a crank but no start or a hard start/long crank condition. Some 7.3L Econolines with aftermarket modification to the electrical systems may exhibit "chattering" of the Injector Driver Module (IDM) relay. This may be caused by modifications to the vehicle which may not provide enough electrical current to maintain the function of the IDM relay. ACTION: Run a dedicated power source to Pin 85 of the IDM relay. This action will isolate the IDM relay power circuit from any circuits that may have aftermarket equipment connected to them. Refer to the following Service Procedure for details. SERVICE PROCEDURE Check for 12V at Pin 87, Circuit 876 in Start or Run, and during cranking. If 12V is present in Start, Run, and during cranking, proceed with normal diagnostics. If 12V is not maintained during cranking, proceed to Step 2. Check Powertrain Control Module (PCM) ground wire connection for corrosion or poor contact. Ground in the circuit is G101 on Page 151-10 at location E1 in the 1998 and 1999 Econoline Electrical and Vacuum Troubleshooting Manual (EVTM). Ensure proper contact. If concern is not resolved, perform Step 3. Run a 10 gauge wire from the starter motor relay post (Battery +) to the engine compartment fuse box. Install a 30 amp sealed fuse in the 10 gauge wire. Cut the wire that attaches to Pin 85 of the IDM relay (Relay F) in the engine compartment fuse box ensuring that enough wire is left to splice in the new 10 gauge wire from Step 2. The wire to be cut is Circuit 361 (non-electric fuel pump) or Circuit 16 (electric fuel pump). Attach the new 10 gauge wire to Circuit 361 (non-electric fuel pump) or Circuit 16 (electric fuel pump) using solder and heat shrink tubing. Cover the unused end of Circuit 361 or Circuit 16 with heat shrink tubing to prevent shorts. Secure all wiring and test vehicle ensuring that 12V is present at Pin 87, Circuit 876 in Start, Run, and during cranking Somebody performed this tsb due to this issue above.there dedicated 12v supply was building corrosion.i just jumper it to another 12v hot at all times.fixed it. Thanks for your help everyone.

Just dies without warning.doesnt stumble then die.Fuel pressure good and quality good.ill try monday with the idm.

wow.good info guys.Yea the school buses are just rolling in.Yippi.Powers and grounds all good.fuel pressure and quality good.f-series idm okay to swap in e seriees.its a 99

school bus.dies at stop.restarts fine all the time.cmp replaced.only code p1670.what have you guys seen out there.Any known concerns?

well ive done it both ways.i perfer doing it in chassis.ive done about 7 of them,none came back.

hotline told me there are issues with cylinder 2.Im working on my second motor on the same vehicle.Meltdown cylinder 2 both times.putting in a pcm this time.

has anyone seen any 07 lcf on the lot.I wounder if they stop producing the lcf??

Had one where it would sound like small little pops through the intake slightly reving.ended up being camshaft lifter.

maybe overfueling.?

oh yea. the oil leak was coming from the front seal.Seal stickin out a 1/4 in.out of housing.probley pushed out by all that crankcase pressure... /forums/images/%%GRAEMLIN_URL%%/thumbup.gif

got one in for oil leaks and runs rough.had codes for cylinder 2 cont. and missfire #2. had koeo for glowplug #2.powerbalance #2 droping.relative compression down some on cylinder 2 and 7,which #7 prob caused by readings of #2 since its next in the firing order.sft cylinder 2 at 25.pulled out glowplug and found tip melted.I just figured injector overfueled and washed cylinders down some.I was hoping after installing new injector theyll pick back up.It didn't.Did manual compression test,cylinder 2 150psi. inspected valve train,nothing broken.Removed cab for first time.Not that bad,made it pretty simple.removed turbocharger and removed bank 2 cylinder head.Found piston melted.Melted a hole in the piston.There sending me a complete,since threre are no short or long blocks available yet.

yea,they told me the pipe starts to melt at 315 degrees.It wouldn't let me go much pass 282 degees.just kept downing the power.maybe if he was pulling trailer...

got a truck today.lack of power.would not go over 35 mph load.no codes found.road test up steep grade.notice fan clutch on early but ect-192.started to loose power.would not go over 36mph.monitor eot-282 degees.pcm cutting back power.never seen it before.something new /forums/images/%%GRAEMLIN_URL%%/cheers.gif
