VP-44 Failure?

Posted

Hi guys

 

First off thanks for the add this looks to be the place for 2nd generation questions.  I have a 98.5 24 V that stopped running.  It was running ok and I parked it for about 10 minutes, wouldn't restart.  Turned over fine just wouldn't fire.  Changed the fuel filter and bled the system.  Cracked the injectors and only got fuel out of cyl 3 and 4.  It seemed like it was only the lift pump pushing fuel not the injector pump, fuel just ran out when the lift pump was going.  Pulled it and managed to get it started (have to love a 5 speed).  Had a major stumble on the low end but once you got going it did ok.  Not great but got it home.  It would die if you let off the pedal but as long as you kept it above 1500 it would stay running.  Pulled the codes and had the following P1693, P0336, P1689, P0216.  I did the hotwire test and it would make a faint click sound when you energized the pump but it wouldn't start.  I'm thinking the VP-44 finally died at 252000 miles but I don't want to spend $1500 if there is something else I should look at. Thanks guys

    By the time you pay the $4k for the pump conversion and install it. I'll have enough money to purchase a MILLION miles worth of VP44's and meet you at the other side. But even p-pumps don't last forev

    See the little  guy at the end of my sentence? That means I was making a joke. It's my way of at the 12v guys who say VP44's are unreliable. No way I'll ever P-pump my truck. I like my tachometer.

1st - 50k miles

2nd - 243k miles later.

3rd - still going.

 

Both mine failed with P0216 codes. But different failure. First one was a true lift pump and timing piston failure that stuck in retard. The second was timing piston failure this time was reversed. This time it was stuck in full advanced and knocking quite loud.

Could be worse just by 2003 or newer truck and have to replace $4k worth of injectors every 100k to 150k miles. VP44 pales by far to the cost of CR injectors. :spend:

Yep, your right I can still get a set of new Bosch  RV275's for $360
