Hi Mikey; Did it come with software, and does your elm327 read ABS or Airbag codes? If not, is this just a matter of finding the software that could? Thanks for your help so far, Peter

Hi Every one; I'm looking for an economical way to read trouble codes, including ABS and SRS (air bag). I see "ELM327 USB scanner" cables for sale on the web at incredibly reasonable prices. Is anyone using their laptop to read codes and do you have recommendations for hardware and...

Thanks ECSS; I think I should read my GM manual, the entire section on 'ASR' and Traction Control. I would like to remove the diaphragm unit for the Cruise and also the motor drum assembly, I assume for the TCS. I realize there may be issues with computer fault codes, etc. There is a TCS...

Finally fixed! Just to update: Installed new fuel pump and strainer sock. Pressure now 42 psi when key is turned to run, (when pump runs for 2 seconds). Car starts great. I saw fuel leaking from regulator. Replaced fuel pressure regulator. Everything perfect now. I believe I did not...

Update; What felt like 'grit' inside of the filter screen, was actually an inner layer of coarse mesh.

Thanks ECSS; Thanks for sharing your detailed knowledge. I will inspect the tank today, and remove the filter screen 'sock'. Unfortunately the tank is about 3/4 full. If I see and rust/etc in the tank, what do you think of rigging up the old fuel pump to vacuum the bottom of the tank. I...

Hi ECCS and Everyone; Still struggling with my C-4 fuel pressure problem. I finally removed the pump sender unit. I may be on to something! The screen sock on the bottom of the pump is oriented diagonally, and seems to have a lot of 'grit' inside of it. I read that it has to be installed...

Hi Folks; I just replaced the fuel filter. I turned key to 'ON'. Still only 18 psi at the schrader valve. Is it time to pull the fuel pump assembly? Thanks for the video link ECSS, doesn't seem like too big of a project, even for a C-4 novice. PS; I turned ignition on, with fuel...

Hi Again ecss; It was easier to ask dumb questions, than get my hands dirty. The car is up on ramps, my filter is very accessible. The car (96 with LT-4) has stainless headers with 'hi flow' cats, further back, not beside the fuel filter. I watched a video, can't find it now, but someone...

Thanks again for all the help,everyone, and Happy Easter! I am beginning to suspect the fuel filter, I have rejected the idea so far because it seems fine, accelerating etc. once it starts. ECSS; your link above, re; fuel pressure measurement was relevant, same year '96. This morning...

Should have been more clear; With the engine running, the pressure cycled between 34 and 40 psi. Opening throttle did not seem to affect fuel pressure. To be honest, I did not have the nerve to put the peddle to the floor, with no load on the engine. Could I not just disconnect the vacuum...

Does this mean something to anyone? I got the gauge, and found the following readings; Connected the Gauge: 0 psi Turned key to 'Run': 18 psi Turned key from 'Off' to 'Run' several times, thing I could "bump up" the pressure with the 2 second pulses: no change stayed at 18 psi, even waited...

Can I waste your time with a few more dumb questions; A; If the fuel filter is dirty; wouldn't the fuel pressure still develop with repeated cycling of the ignition key. If the engine is not cranking, the injectors will not reduce the static pressure. B; Would blocking the Fuel return line be...

Thanks again ECSS, for the great info; I removed the vac line from the fuel pressure regulator, then cycled ignition key from off to run, about six times. I heard the pump running for those 2 second pulses. No gas found, coming out of the regulator. I will pick up a fuel pressure gauge...

Hi ECSS; I disconnected the sensor (top rear of block) It has a red, a yellow, and a tan and white, as you mentioned. The other sensor has a green(I think). The single wire sensor was left connected. The car started reluctantly as usual but idled fine once it started. Oil pressure gauge in...
