'93 S10 Blazer Fuel Pump ??

[98Z]

I took my Blazer to a local shop because I'm tired of screwing around with it trying to make it run. It started with just being difficult to start every now and then. Slowly, it changed to being hard to start all the time. I'd have to try starting it like 20 times before it would finally start and run. Then it just wouldn't start at all. I've done everything else to it already: plugs, wires, cap, rotor, ign. module, fuel filter, and I even changed out the injector spider with another one I had.

When it was running, the check engine light had been coming on. It would come on shortly after I started it and would remain on for about 1 or 2 miles, then would go out. Checking the codes would only give me a code 43.

Anyway, when the shop called me today, they tell me the fuel pump has abour 40 PSI and the Vortec engines want more like 65 PSI, so they want to change the pump... at a low, low cost of only $297.00 :22yikes:

Now, IF I were to try to tackle this job myself, how much of a headache am I getting myself into? I had a '91 that I was going to change the gas tank on, but I couldn't get the strap bolts to break loose. I broke 2 sockets trying. I never did change it.

Anyone have some advice??

Sounds like the problem I am having with my 95 S-10 Blazer.

I have a very hard time starting it during the summer months and absolutely no problems with it at all during the winter. I have replaced the O2 sensor and a torn gut from the air intake assembly and it fixed the problem only for a period of 24 hours. Runs rough, wants to stall when coming to a stop, service engine soon light comes and and then then next day everything is fine and light goes out on its own??? What's the problem here? Any advice?
Have been told fuel pump, fuel injectors or could be several other problems.

Don't post your questions/problems in more than one thread. This is 98Z's thread, you already have your own.

Everyone, if you'd like to reply to Michael Wallace's problem, please do so in his thread.

Seems you've had enough stress with it on your own. I'd let the shop do the work. I'd ask if they give any type of guarantee that it will solve the problem.

That's a good bit of advice. I'd hate to spend 3 bills and then find out that I need to spend more money because that wasn't really the problem.

As for the stress it's caused me... It had the brutal 1-2 shift that these things seem to be notorious for and I had a local tranny shop take a look at it. After some screwing around with it, I was told it needed a tranny rebuild. So I took a spare tranny that I had down to them, they rebuilt it, installed it, and it still that the brutal 1-2 shift. They said they now needed to change the computer ("because it's the only other thing that it could be"), so I took them another computer I had (I parted out a rolled '93 for the black interior, so I have lots of parts laying around). That fixed the shift problem. So, I have a $1,600.00 computer change that I could have done myself for free!

All I want to do right now is get it running right so that I can sell it and pay off the loan I have against it for the new tranny. I was hoping to get a little extra out of it, but it seems that it's just going to nickle and dime me to death!
