Will the lift cylinder still function if I have a line hooked wrong

P1353 Valve lift control cylinder X - small lift
Possible fault causes:
- Fuel injector faulty or borderline (opens too late/ not long enough/ not enough/ leaking)
- Valve lifter of the specified cylinder faulty (intake valve of the specified cylinder gets stuck during the small lift)
P1372 Valve lift control, bank 1
Possible fault causes:
- Insufficient oil supply for faulty bank 1 (e.g., due to faulty scavenging restrictor in the cylinder head, dirt in the oil circuit, ... )
- Greatly differing exhaust backpressure values between the banks (e.g., due to constricted or blocked opening of an exhaust branch)
- Loose contact or corrosion on connectors or lines
- Solenoid hydraulic valve for valve lift control on bank 1 faulty
- Incorrectly adjusted timing of the intake or exhaust camshaft of a bank
- An oxygen sensor is aged or faulty
P2404 Leakage diagnosis pump, Reed switch
Possible fault causes:
- Vacuum system leaking
- The system consists of the mechanical vacuum pump (on the vehicle engine), the leakage diagnosis pump, the intake pipe switch-over valve and, where appropriate, the exhaust flaps in the rear muffler
- Vacuum pump has mechanical fault
- Tank vent valve stuck in closed position
- Purge-air line between tank vent valve and carbon canister blocked
- Short circuit to B+/ground or open circuit in signal line
- Leakage diagnosis pump faulty

check for air in cylinder may have to bleed the line and cylinder

There is a factory vacuum diagram under the hood, we do not have diagrams.

The lift pump in a diesel engined vehicle is designed to 'lift' fuel from the fuel tank to the injector pump.

Sounds like you may have a hydraulic leak somewhere. Check the rear wheel cylinders and front brake hoses going to the calipers.

Your going to have to replace and flush the entire system, Master cylinder,
rubber brake lines,calipers and rear brake cylinder if equiped, your saftey is #1

These and Blazers were notoriously hard to bleed the air out of the system. I actually had to make up a clutch reservoir cap with a nipple on the top so I could hook it up to a vacuum pump. With the system full, try to attach a vacuum pump (hand operated one works fine) over top of the reservoir, or if need be to the feed line to the master cylinder. Apply vacuum until you can see fluid, soon you should see bubbles in the line. Maintain constant vacuum until all air is gone the system should be fully functional after that.

Make sure all lines are light when turning engine over.While turning engine over loosen the a line closes to pump or the fuel filter.You should get some fuel.Then continue on all lines working farther away.

your lines are in a 5 groove holder plastic clip on the drivers side by the back door,if you could have use of a lift it is visible to follow it from the left wheel cylinder around the gas tank.

The master cylinder supplies the pressure to the brake fluid that travels between the maste brake cylinder resevoir and the brake caliper pistons (through the brake lines. If the master cylinder fails there will be insufficient compression of the brake fluid to make the calipers operate as designed. Leaks in the brake lines and/or cylinders is a possibility, and unrelated to functionality of the master cylinder. Also, pistons located in the brake calipers can form a corrosion ring on their inside walls if there is breakdown in the brake fluid or moisture that gets into the lines. Operating the vehicle when there is insufficient brake fluid in the master cylinder resevoir can also lead to air getting into the brake lines, causing bad working brakes. Air compresses more than brake fluid, and the master cylinder isn't designed to compress air in the brake lines. Sounds like a bad case of "lack of maintenance", as opposed to bad advice from the mechanics. That said, there's no excuse for bad installation. But, it's tough to improperly install a brake line since they are nothing more than hollow metal tubes. There should be no rubber connectors installed in the brake lines. When bleeding the brake lines one must remove all of the trapped air before you will see any fluid appear. If the valves in the master cylinder are not properly operating the master cylinder will not allow the brake fluid to get into the brake lines.

Hope this helps.
