Motor died while running, now no-start

[VetteMed]

Took the Z out this morning, was running really well - probably the smoothest it has run since I bought it. No sign of any issues for the first 3 or 4 miles. Stopped at a light, then took off gently. got up to 30- 40 mph or so, then nothing - pushed in the clutch and the motor was dead. There was no warning, no stumbling or hesitation.

It cranks just fine, but doesn't fire. Just got a tow back to the house, going to let it cool off a little and start troubleshooting, I suppose... :confused:

Maybe primary fuel pump failure. Make sure your also not out of gas before you get too involved you may have a faulty fuel sending unit and simply ran out of fuel .

You might be on the right track -- no fuel pressure, even though I hear fuel pump priming. Now, this pump has maybe 200 miles on it since new from the partsladi. Filter is also only about 200 miles old.

Top her Off bro!!!!!!!!!!!!!!!! Let us know a whole team is here to help !!

Plenty of fuel in the tank -- I can see it in there thru the filler neck. added a gallon anyway -- no different, still zero at the fuel pressure gauge, nothing if I push in on the schrader fitting at the rail.

Swap the secondary fuel pump as the primary. I think you lost the primary fuel pump. The swap will be the confirmation.

Also the Partsladi is a great vendor. if its new pump I would bet a beer they would replace it for free.

I seem to recall there being an electrical way to do that, without pulling the pump assembly out of the tank?

Thanks

Andrew I dont think so. The Primary pump is the higher of the two you have to physically swap the lower pump within the housing. I am not 100% positive since I have not peformed this job yet. But I am pretty sure thats the only option

The only other Fuel delivery area to look at beyond the pump is the fuel metering block/valve behind the plenum.

OK, I'll get started on swapping the pumps. Thanks for the info Daryl.

Before you get the fuel pumps out, try energizine the fuel pump wire off the main harness. It'll be by the ECM, and be a red spade connector. Hit that with 12V from the battery and see if you get pressure.

What I think you are seeing is the primary is dead, the car ran for the first 5 minutes or so, because the secondary pump was running as well. Once it reaches temp, it shuts the secondary pump off, and will leave you stranded.


If you have some electrical pin tools, you can swap the power leads for the pumps in the back.

[GOLDCYLON]

Spoke to Jeffvette he said you would have to start pulling the electrical pins and swap them around to make the primary the secondary or run some patch cables around but would be probably easier to just swap the pump. He said there is also a procedure to jump wires next to the ecm to have both pump run at the same time. Not sure where that is although. He beleives the pump is the culprit as well. GC

Thanks for the info, Jeff. I swapped the pumps already, and got better fuel pressure than I ever had before (when I first installed the pump/sender assembly new out of the box, I got around 40-41psi. I figured that was low, but the car seemed to run fine...

This time, with the pumps swapped, it ran up to just under 50psi, I heard the regulator bleed off a little pressure, and it settled in around 45psi.

Guess I need to fire off an email to the partsladi now.

Thanks Daryl and Jeff!

No sweat ! :cheers: I suggest calling them direct they are in FLA too!!

Edited after I had time to cool off...

Apparently, if you buy something from partsladi, save your boxes and receipts. These are both needed for warranty returns.

[GOLDCYLON]

OK, well, partsladi is off my list of acceptable vendors.

Here's the deal: If I don't have the original box it came in, they won't do a damn thing for me. SO I guess we're supposed to save every box from every part until the warranty runs out ( 2 years), in case there's a problem. :censored:

This makes me hoppin' mad.... for a "reputable" vendor, that's unacceptable IMHO and I won't be sending them another dime, ever.


I can ship you my empty fuel pump box. Well it will be empty when I remove the pumpladi fuel pump out of it that is. Just send me your empty when it (replacement pump) returns. It came from the Ladi. Do you have the receipt?

They claim there's a barcode on the part that has to match each individual pump -- I'm calling BS on that, I don't see a barcode anywhere on the pump or sender assembly. I'm tempted to just buy the Suburban pumps elsewhere and be done with them. This assembly was made in China anyway, which made me a little leery when I installed it. :mad:

I suggest giving it a try. If you have the receipt the pump and the box I think they would be hard pressed to deny your replacement. You did buy it from them. They are just going to ship it back to the manufacture anyway. It not like we are trying to screw the vendor your just meeting their anal requirements in this case. I dont buy the barcode arguement either. PM me your Phone number

Can't find the receipt... I just moved a few months ago and I guess it got misplaced in all of that. :dontknow:

Did you buy it on Ebay and use Paypal?

[GOLDCYLON]

Well crap my pump was in a Corvette Central box. If you can hook Andrew up please pm him thanks GC
