That should go to your oil pressure sensor, located behind the power steering pump.

The increased ability of coppers to dissipate heat is one of the reasons they are preferred on high pressure boosted applications. On extended high power pulls the tip of platinum and more so the fine tip of iridium's can become a source of detonations and even pre-ignition. It is the reason you...

Hey Matt, as of five months ago Toyota of Escondido was able to cut me a new key from the VIN number for my 92 MKIII. You might check with the Burlington dealer up there to see if they can pull your code from your VIN. Maybe US dealers keep them longer than Canadan ones. Never hurts to check.

Test it. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=FI&P=119

TSRM states what it should be and the TCCS makes fuel calculations with these baselines in mind. The only need to deviate is if at some point the AFR's get to rich or lean and you have no other way to correct the fuel trim, as adjusting the fuel pressure makes across the board, general changes...

That fuel pressure is a little high. Was that number determine necessary through tuning, and monitoring your AFR's. Normally you start at 33-40psi at idle with the vacuum hose off and plugged. Then when you attach the vacuum hose it should pull it down to 23-30psi. So you are going to be...

Are you still running the Lex/550 combos like your profile states? What do you have your fuel pressure set to?

Have you checked for codes? http://www.cygnusx1.net/Supra/TechTips/engine_error_codes.aspx There is a very good flow chart located here for for things to check in the event of stalling. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=FI&P=14 Also a malfunctioning dashpot...

That car has lived it's life of usefulness as a whole. Let it go quietly and keep looking. I'm sure it will serve a far better purpose as a parts car, than an absolute migraine wallet drain in your hands.

All model years of the MKIII had a power steering cooler. Up until 91 it was just a metal length of pipe behind the front bumper. Then in 91(04/1990) they updated the design to be a longer loop and to have cooling fins. The redesign was applied to all turbo cars. However on non-turbo models the...

Yeah that would do it. Bummer. And I'll admit, I never looked under EGR vacuum solenoid for it, wonder why.:dunno:

You sure your thermo time switch is bad? The're not known for going bad. It won't kick back down to a lower resistance value until the coolant gets below 15°C(59°F). Going by where you list your location as, its entirely possible that the coolant didn't get low enough to rest it, even if sat...

Got ya, I miss understood when I first read that sentence. My apologies. As far as measuring the frequency you take the reading from The KS & E1 pins. With the engine running, you are looking for a relatively stable frequency, and for it to increase proportionally with airflow. If the...

THA & E2 should be showing a reading, however if there is an open or short between those 2 the the ECU will throw a code 24. The AFM houses two sensors, one is a air temp sensor, and the other is an opto-sensor that uses a mirror and a vortex generator to meter air flow. The THA and E1 pins...

Ok if that site is accurate then you need to run these wires to the ECU: OBD2______ECU Pin2------->F60 pin 11 Pin5------->B2 pin 17

I havn't done it myself but I can tell you that is the wrong cable. The one you have shown plugs into the OBD2 port. You need the other end. The female end. Something like this one: http://compare.ebay.com/like/151012379632?var=lv&ltyp=AllFixedPriceItemTypes&var=sbar Next you need to...

To avoid confusion the stock electronics use an AFM to meter the air. A MAF is a different method of metering air entirely. It can be used on a 7M via a popular piggy-back electronic. That is why you will see a MAF referred to on here. But if your on stock electronics then we want to check the...

Like 3p141592654 said you really need to get those codes. Also what fuel system upgrades did you do? Is it just the FPR, walbro, and DM lines. Did these DM lines include the J-tube delete? You also might want to get rid of that K&N filter, the oil charge they impregnate the cotton medium with...

Or enlist in the Imperial Stormtrooper Marksmanship Academy .

To be honest, having not owned a Cali spec 7MGE, I cant tell you for sure where it is located. Some people say the connection is under the driver side seat. But I don't know for certain.
