DI Sputters, Backfires and Dies.

[rrc.swb]

I left my 96 Disco sitting too long and it's acting up.

I did the head gaskets, all hoses, plugs, and wires about a year ago.

The truck hesitates to start. After four or five tries, it will start.

The truck will idle smooth. If any throttle is applied it will sputter, backfire and dies.

I've read that this is common and that the ECU might have water in the connectors. I checked and they are dry.

Any suggestion?

Check the fuel pressure and the connections at the pump.

 

[rrc.swb]

No pressure. The fuel pump is not making any noise either.

I'll check the pump tonight.

Mass Air Flow sensor?

 

[ptschram]

Power to the pump when key first turned on?

 

[rrc.swb]

Sorry for the late response...

Mass Air Flow sensor?

I need to see how I can check that, because I have no MIL codes. I'll try cleaning it with the CRC MAF cleaner.

Power to the pump when key first turned on?

I was not able to hear it running and didn't check for voltage.

I went ahead and ordered the E3270 non-Rover fuel pump and am waiting to get it.

The interesting thing is that yesterday I went to start the truck for shits and giggles... Guess what, the motha trucka started on the first crank.

The truck idled smooth, applied throttle it did sputter, backfired and died. Cranked it again and started right away. I let the truck run for 15-20 and idled fine.

I didn't have my tools with me to check fuel pressure or voltages. :banghead:

It's the pump.

 

[rrc.swb]

It's the pump.

Glad to see this.

I'm replacing it Sunday and will update ya'll.

I left my 96 Disco sitting too long and it's acting up.

How long had it been sitting?

 

[rrc.swb]

How long had it been sitting?

6-8 months

 

[rrc.swb]

Problem solved. It was the pump.

Thanks guys!!!

 

[ptschram]

Next time it fails, I have the complete assembly in stock.

Next time it fails, I have the complete assembly in stock.

Thank you! I'll keep you in mind.

If it dies again, it's the 2-ft long harness plug to the pump that needs replacing (they corrode and die).

 

[riceybean]

I had to run a fresh wire from the shut-off switch to the new pump after a couple of weeks of the new pump being installed.

 

[rrc.swb]

If it dies again, it's the 2-ft long harness plug to the pump that needs replacing (they corrode and die).

We'll talk about that at The Conclave.

Thanks dood!

 

[ptschram]

I have that harness as well.

NEW, OE.
