Can't figure out why my 88 4 cyl won't start.
Replaced a dead fuel pump last year and it was running but flooding.
Appeared to fix that issue, it was vanish and gum in the plate.

It now appears the fuel pump is dead, likewise the fuel gauge suddenly is dead too.
It has fuel but the needle won't budge.

Checked volts on the pump and it has volts but I don't hear it priming when the key is turned.

Plugs are dry so it's just not getting a drop of fuel.
I have a few fuel pump relays I tried, made no difference at all.

What am I missing?

If I can't get it running to sell it has to go to the junkyard which would be a shame.
It's 28 years old and beat but still solid enough to be a daily driver if fixed.

try giving a pump direct 12v, come back with results
also, did you replace the filter when you replaced the pump?

egp320i

Filter was changed not that long ago. It would have to be really clogged to cut off 100% fuel with pressure.
Just odd the fuel gauge worked when it least ran, now it's dead and so is the car.

CIS is fairly simple until it stops working and you can't figure out why.

Worse, all the parts are on the more expensive side even used to troubleshoot.

just for ****s and grind, dump some gas in the tank, or pop the pump out to check the level of the gas... i know it sounds stupid, but who know. and ive spent 2 evening trying to figure out what the hell is wrong with the car just to realise that the owner ran the car out of gas.

CRAZY_RUSSIAN

and yeah, i completely agree with you on CIS, i usually try to stay away from that system

egp320i

I dumped about 2 gallons in, it has fuel but not much. It looks like after 28 years the fuel level sender took a dump.

I checked volts from the leads and I have 12v when it cranks which pretty much proves the aftermarket fuel pump with zero miles already took a dump.

Guess this is what you get for buying junk from ebay. It was new OEM spec or so the claim was.

I only needed one that worked so I could sell it, I did not even get that far.
The thought of tearing that part of the fuel system again is not thrilling, least it should come apart easier now.

Surprisingly the only bosch local to me is from some 1985 4000. Paying 45 bucks for a 30 year old pump is rather dumb.

zero B3's around me, kinda surprised by that.

its a gamble with used pumps, but autohaus want about 110 for one :-S but it might be worth it
on a fuel sender, its most likely just a small wire that allows the sender to pivot up and down, they are known for braking, easy replacement and fix

egp320i

I agree, wish it was less in cost but it's such a pita to replace and mess with gasoline might as well get new.
Just trying to determine if it's worth it at this point. It has sat for a few years due to a leaking torque converter seal. That is about a $500 job.
Not a dribble, it leaks really bad.
Tried selling it local as a project car and only had tire kickers.
Local yards are not interested even though the 2.0 VW motor was popular in many 80' VW's so it should have some value.

CRAZY_RUSSIAN

fix it parts are cheap and pulling a 2.0 is much easier then pulling an i5 or a v6

egp320i

Ha, called my local yard and they said steel is so cheap they are not interested in it, not even for the 2.0 motor which they currently do not have in stock.
They said about $125 is what they could offer with me towing it.
Guess I have a fuel project coming up. Maybe I can find somebody on the forums tearing apart a 90 who has a good working pump they can sell for cheap.
