Have you tried Dave Bean Engeneering in San Andreas, CA?

with the engine cold remove the turbo outlet hose and check for free rotation of the spindle. if it is ok check the wastegate capsule link arm mechanism is not seized as this is fairly common. if all is ok check the pipe work from the turbo outlet to the intercooler (lh side below airfilter headlaamp area) then from intercooler through up to inlet manifold. if all is ok, get a manual pressure gauge on the take off port at rear of inlet manifold should be a pipe blocked off with a rubber bung (lh side back of manifold) (lh side is gear box side of engine) drive car an see what the gauge reads. if it is registering boost then is often the manual boost transducer module on the right hand wheel arch by the cam belt cover that is not working so boost is there just does not register in the car.full boost is not achieved until car is at normal operating temp. if no boost turbo may need checking for wastegate operation or damage on the exhaust side. Hope this helps

you meant does not crank, (starting is next after cranking it first) the gear shift works in park or neutral , you operator guide states that. yes that means the PRNDL switch in or on the gear box is bad. or wires to it corroded pins or damaged, also called range switch. or TRS , tranny range switch, easy no? you found the hard proof and told it. when bad switch or bad wires to it.

it is in and or under the back seat. put it toward the middle of the car. if not you will brake it and the truck will not close. So you might want to go to the dealer to find out if there is a fix now to get the cable replaced so if you try to open it the wrong way at least you can close the trunk

There is a manual trunk release that is inside the car near the rear seats. You must make sure to pull the release towards the tunnel/middle of the car, not out away from it. Apparently, a number of sales people have tried to demonstrate it and by pulling on it incorrectly, broke the inner workings leaving the trunk then incapable of latching closed. The repair is not simple. Something about the cable being encased in a tube that is not straight but curved, so that when you pull on it the wrong way, it breaks something. Lotus is redesigning that component. Also note you may need someone to gently lift on the trunk as you pull the lever. It should be a yellow lever.

The usual culprits are bad ignition relay, bad module or coil(s). Ignition switch also possible.

sounds like the coil packs , get the OBD codes read to confirm

Normal operating temp for any car is 150-170 F, Your thermostat is set for these amounts, water boils at 220 F and coolant boils at 260 F, but the boiling of anything in there is not good, it creates pressure, something is going to give. Your radiator cap has a temp on it too, about 165. It will bleed off the pressure before it explodes. So, you can check your thermostat, they do freeze up, check your coolant, don't run straight water. and then check the inside of your radiator, they do clog up. Hope this helps.

You need to determine where the noise is coming from. Check your power steering fluid and make sure it is full. Remove your serpentine belt and see if the noise goes away, That will let you know if it is coming from the engine or an accessory or pulley bearing. If the noise goes away whith the belt removed, check the alternator bearing and pulley bearings. If the noise is still there whith the belt removed, that means it is either in the engine or transmission.

what car, year,maker ,model power to switches are fuse blown. on old cars. then 2007 to 2010 there is no fuse the BCM body brain runs brake lamps direct and a small voltage digital signal from the switch totally differ ways on new cars is this a trail lamp issue? tell car and I will show you the brake schematic from the online FSM book.

To check for a coolant leak with a radiator pressure tester, the engine does not have to be warm. In fact, it's safer to perform the test when the engine is cool to avoid the risk of burns. Here are the general steps to perform a coolant pressure test: Make sure the engine and the system is cool since hot coolant can burn, and that the cooling system has no pressure. If the coolant level is low, add water or coolant to raise it. Remove the radiator cap once the system is cool and depressurized. Connect the pressure tester to the coolant reservoir or the radiator. Pump the pressure tester to apply pressure to the cooling system without going over the system's psi number on the radiator cap, which the pressure tester's gauge measures. If the pressure gauge drops quickly, there is a leak. The slower the gauge drops, the smaller the leak. As for your Buick, it's possible that the intake manifold gasket is leaking coolant. This is a common problem in many GM vehicles, including Buicks34. The coolant can leak externally, or in some cases, it may leak internally, causing coolant to mix with the engine oil. Operating the engine with a coolant/oil mix can result in internal engine damage. If you suspect this is the case, it's recommended to get it checked and repaired by a professional mechanic.

A mechanic's scan tool would lbe necessary to check all the modules. The problelm could be either in the wiring or the control modules. There is also the chance the dimmer switch could be turned off or defective. Or, the electrical part of the ignition switch could be problematic. Because of the possibilities, use of the scan tool would seem the route to go.

need to get a repair manual or go to library for mitchell and chilton series-sec629

some bolts on things like this are LHB left and bolts. righty tighty and leftly loosey fails. best is get the service manual and check it out. no shaft told, at all, photo work easy here. good luck !!!
