From what I’ve seen on here, the consensus is that the Bosch fuel pump is the only one that won’t die immediately
Yesterday I changed the fuel pump. After changing the fuel pump, I put the pump relay back in, turned the key to ON and listened for the pump to prime. After about 3 seconds, I turned the ignition on and the car started right up! I shut it off, cleaned up my mess, and about 20 minutes later I hopped in and started the car again. No issues. I drove it around the neighborhood and the thing runs great! That cutting out/lag/surging was gone, the engine felt powerful again, and the fuel gauge was back to working.
Hopefully I can get some more years out of this Bosch.
044's are awesome pumps, and rarely quit
044 can take A LOT of abuse. They are OEM spec
I reset the timing to 1.0mm left every else as is, and accually got the cold start lever hooked up properly with a spair part from another pump i had laying around
044's definitely do not suck, they're regarded to be very reliable probably more so then any other EFI pump on the market for many, many years now.
This is true, the Bosch pump is loud, The Walbro is kinda loud too but it is totally bearable, At idle is whines but thats the only time you will hear it..
After wiring the fuel pump relay terminals together to bypass the relay entirely, after 40 miles of heading back towards Arkansas it died on me again with the exact same behavior as before.
Learn from my mistakes. :facepalm: Although as shown on the link above that Bosch lists this pump as for the Mk4 R32... it is not correct. Some things you don't notice until you are halfway through the job.
