I bought the sy today #238 and drove it home and this is the list

Fixed
Tranny pan drop and flush
Change oil
Changed fuel filter
changed spark plugs
and some lil TLC stuff

Needs to be fixed and all input is welcome on how too's

coolant line to from the IC that runs to the lil pump under the bumper by the air pick up the fitting is broke off on the pump part so my guess is i have to replace it and two black wires are just hanging there.

theres a plug that is unpluged resting ontop of the driver side valve cover and i dont know where it goes my coolant gauge doesnt work and i found that the wire runs to the plug but dont know where it goes. is it supposed to be unpluged since i have the 3 bar ultimate chip i wouldnt think so but i dont know thats why i ask.

HELP Wanted

Thank you...

Re: Bought the SY and has problems!!!

That plug is probably for the coolant temp sensor.(which is why the temp gauge isn't working)
Just look on the drivers side of the block.You can't miss it.
Should be throwing a trouble code too,and running like shit if that sensor isn't hooked up/working.

Re: Bought the SY and has problems!!!

yeah, that sensor wire is one green wire in its own wire loom. You maybe getting a check engine light, but unless the ECM makes the truck run like crap with the CEL on, that sensor won't have any effect on how the truck runs; it goes straight from the sensor to the gauges. The yellow/black 2-wire coolant temp sensor on the lower intake is the one tied into the ECM and provides the temp for fueling and what not....

no this is a big plug the coolant temp wire runs to a group of wires ontop of the valve cover and runs towards the firewall and the plug comes off of the group of wires and i can find where it plugs into.

Whoa, didnt realize you got #238. :tup:

Thats a truck on my list for future ownership (sequencial numbered trucks), so you best fix it and keep it in good condition.

That thing has different gears out back too if I remember correctly?

Re: Bought the SY and has problems!!!

If the plug has three wires (black with white stripe, grey and red with black stripe) going to it that is for the EGR valve. If you have an Ultimate chip, it will throw a code if you run the T1 15 psi program. In all the other programs, the EGR is disabled. I run T1 16 psi on the steet with pump gas. Many people remove everything associated with the EGR to help clean up the engine bay. However, they usually don't cut off the plug. They tuck it somewhere out of sight.

With regards to the IC pump, you can get a new one from Ron Gregory in Garland TX here. He has been around these trucks for a VERY long time. He also sells Walbro fuel pumps, boost gauge fittings, Phil Chiver's driveshaft safety loops and hood prop eliminator kits.

Your profile doesn't list where you are located at but if you live in warm climate, driving a truck with an inop intercooler WILL make it run like poop. If you are really "lucky" the ECM won't be able to retart the timing enough if you start detonating and you may get to put connecting rods through the oil pan... Folks that were unaware the the IC pump wasn't working were amazed after they got it fixed. It makes a HUGE difference performance wise. Putting your Ultimate chip in the "valet" setting will keep you out of trouble until you get it fixed.

After you get your new IC pump, you can use a paperclip to jumper the "A" and "B" terminals on the ALDL to turn the pump on. The ignition must be in the "ON" position to do this. If the pump doesn't run, check the fuse for it:

"intercooloer pump fuse location behind alternator. Fuse is in a weather pack connector and the top has to be opened to expose the fuse."

Your vacuum lines are incorrectly connected. The EGR should be connect to the EGR solenoid. If connected to a vacuum source, The EGR will premanantly be on as long as the egnine produces enough vacuum to open it. The vacuum you may have connected it is the fuel pressure regulator. I would recoomend you replace all your vacuum lines and route and connect them properly. You could damage the motor with the wrong/broken vacuum connections. The vacuum lines also dry out and leak over time. For almost all SyTy (except for practically new ultra low mileage trucks) they is highly recommend first saftety modification.

this should help with the vac line routing.
