    Minor issues after engine work

    Does anyone know for sure that this assembly fits our 88-89 cars? I haven't seen any cross-reference that shows this. https://www.ebay.com/itm/Fuel-Tank-Sending-Unit-for-Olds-Delta-88-Pontiac-Buick/110724397764?epid=569757228&hash=item19c7b03ac4:g:u~oAAOSww5hZN7Vp

    Minor issues after engine work

    No gas was in the vacuum line for the regulator. If it's a leaky injector, where would it leak from? The bottom in to the plenum? These injectors were totally perfect before removal, and were removed all together (I never removed them from the fuel rail) gently. They are new as of 2012, so that would be another new coincidence. I thought we established a bad pulsator dampener or a fuel-pump check valve was most likely based on my symptoms? It does hard start, but that's because there is no prime-pressure, I wouldn't say it really stumbles at all, just starts as if there isn't enough fuel for the first 3 seconds of cranking and then starts suddenly and normally. I will try to keep the fuel rail connected to the lines at the same time as all 6 injectors are out of the plenum, and I can then run the pump and inspect for leaks.

    It's quite a nice gauge. In any case, it holds about 40psi with the pump-prime connected, and about 37psi with the engine running, but all the pressure quickly drains right out to the tank (I believe) when the pump is off. The pressure increases a few psi with the regulators vacuum line disconnected, so I believe the FPR is working fine. It still feels hard to believe this was just a coincidence after I did all that work, but I suppose it may just be.. especially since the hard starting issue didn't happen the first few times I used it after.. but it did happen after I replaced the fuel filter. (which is not leaking.) So I guess next I need to drop the fuel tank. I wish it were possible to get a whole new assembly because I figure I'll have some rust on the lines. test.mp4

    I looked around on here and I didn't see anything clear, but is there any new replacement sending units/assemblies available for the 89 Reatta? I think the original part was 25094830

    I didn't see your post before I picked up a Kent-Moore one. Cost me a lot, but I could always sell it after.

    My Chinese gauge fell apart, so I can't trust that anyway, need to get a quality one.

    Well what are your thoughts then? If you see the changes that were made, they never involved the tank or pump. My injectors themselves are the same and are very new.

    Alright, I'll focus on my fuel issue then. However it would seem logical for me to focus on 'what changed' last, rather than something totally new. This happened right after I did all that work, which never included anything in the tank. So I need to at first keep my focus under the hood, and no further than the fuel filter (which I replaced) ; the filter isn't leaking. I will check injector seals to the rail. Thanks!

    Also my idle problem is exactly this: (Never was resolved though)

    Tested fuel pressure at rail, getting 36psi, idle. I didn't test under load. I reved it up in neutral and it raised it slightly. Before turning the engine over, the pressure from the pump-prime goes to about 9psi and then quickly falls off.

    I need an external gauge for the pressure right? I'll test it. Also, the temp, related or not, is high I think. I just had it randomly decide to go to 210, then 213, after only 4min of idling. The engine surged a little and it didn't go lower until I started moving. I had already burped the system too. I really don't know what's up. I tried spraying around my intake manifold for leaks and the RPM didn't change, so it doesn't seem like I have a leak there.

    Also when idling high, if shut it off and turn it back on, idle is normal.

    Some more data: Issues are: takes 2 or 3 tries to start, then runs normal. Sometimes after driving, idle is high, 1050rpm in neutral. Tps at idle .44 Mat: 55 Iac: 46 Air flow 6.3 Blm 100 Spk angle is always 0 Deg spark is 23 at idle, 25 under high load, between 43 to 50 when driving normally, and 32 when coasting down. My water temp is 197 when driving and always 200 to 203 at idle. It used to be lower but maybe that's the new thermostat. The engine feels more shakey at idle and shuts off with more of a shake, but I'm not sure still if that's the new crappy engine mount or not.

    Oh ok, it's true that I do believe these Bosch gen3s are a higher rating than the stock injectors are.. (I didn't do these injectors recently, did these in 2012) I just never looked at my BLM before this issue to see what was normal for my setup, oh well.

    Thanks, so those super high numbers are not a problem? The answer to if it increases while driving is no, I've never seen it increment in real-time. What about the BLM, does that indicate I'm running lean? My other new issue is that it doesn't start on first, sometimes even second try, it feels like a fuel delivery issue and I also notice the pump sounds much lower frequency, almost strained when it primes at accessory/on. I had replaced the fuel filter, I wonder if it's defective. Volume seems fine though, as I can go to 100Mph no problem.
