The fuel lines that feed the fuel rail are not screw on nut fittings, both the pressure & the return are disconnected with a set of fuel line/ac disconnect tools. The pressure line is near the centre at the back of the engine. One pulls off the engine cover & you'll see the fuel rail. Once you've disconnected the line you'll need a lengthy section of garden hose to slip over the fuel line end & tape it up to prevent any leaking & feed it into a container size of your choosing. Now you can bypass the relay to power up the fuel pump to drain the tank.

there should be a loose red wire near the relay jump that to the positive post and it should turn the fuel pump on

87 to 30

Does the pump run? If it does, unhook a fuel line under the hood and jump the fuel pump relay.

Hi guys, I'm still alive and well and still have dome light switches! The site used to send me an email when someone posted on this thread, not sure if that doesn't work anymore? My direct email is mezz@benris.com if anyone else is still looking or switches.

Spammer......

absolutely

spammer?

not even a difference ABS/non abs on the gen1 front knuckles. the sensor is separate of the wheel hub - why gm couldn't have continued this into the later cars is beyond me. buy whichever brand you determine to be the highest quality or fits within your budget

Yeah, that makes it sound even more like the brake lights are the turn signal switch in the column... 1994-2001 Gen 1 and Gen 1.5 Turn Signal Switch Replacement | W-BodyTech Forums But that shifting thing...are you able to turn the key and move the steering wheel? Can you shift out of park with the steering wheel unlocked but with engine off?

You should be able to OBD2 swap if you want to go that route, but I'm not sure how possible tuning is with the current options besides what GTP091 mentioned. DHP can still be obtained, but support isn't what it used to be. redzmonte had a turbo 3.4 95 Monte that he swapped the OBD1.5 to OBD2 and tuned. I had tuned my 96 3.4 GP with DHP years ago. I believe you can run a 97 PCM and use HPT, who supports 97+ 3.4 Montes, so I'm not sure how that would work. edit: after some research, looks like you can buy the DHP interface from the original manufacturer (AVT) and it SHOULD work. Setting up DHP on a Windows 10 laptop is a bit of a chore. http://www.avt-hq.com/852_hw.htm http://www.avt-hq.com/price.htm

91 auto which is what I have in my 91 GP is the AYSZ, AUSJ is the T code engine (3.1) W body for 91, AUBU is the T code engine W body for 93 auto trans these all come out of the 16149396 ECM I have nothing on the ASXJ

AYSZ = 1992 LQ1/Auto BBUK = 1993 LQ1/Manual BCFA = 1991 LQ1/Manual BCFA is the one you'll want to use

The 4 memcal's used with the 91-93 LQ1 are AYSZ, BBUK, BCDT & BCFA. BBUK is the early manual trans memcal, & BCFA or *1441* is the later manual trans memcal.
