Fuel pressure testing is an important part of the troubleshooting process when you are trying to determine why an engine is running poorly or will not start at all.

The instructions below do not apply to 1991 models. The 1991 model fuel pump wiring is not the same as earlier models. Consult the 1991 Reatta service manual for more information.

The fuel system is under pressure! Attaching or removing the fuel pressure tester from the fuel rail may result in the loss of highly flammable fuel. Extreme care should be taken to prevent fire or damage to painted surfaces!

The tests below should be performed in numerical order as they are listed on the tabs. Read through each test completely so you fully understand what you are about to do before starting the testing procedure.
