No-Start / Hard-Start Problem 700 1989

posted by  someone claiming to be Bruce Johnson on  Tue Sep 10 05:21 CST 2002 [RELATED]

Both my '88 and '87 are LH 2.2. The fuel pressure at idle is 36 psi. At full throttle (MAP near 0 psi) the pressure increases to about 42 psi, if I remember correctly. These cars use Bosch part #0280160292 which is rated at 2.5 bar(36.25 psi). Your '89 uses part #0280160294. It should be marked with its rated pressure. If it's 3.0 bar your fuel pressure should be about 44 psi at idle and increase with lower manifold vacuum(disconnect the vacuum hose).
The Bosch and Regina FPRs are not interchangeable.

Regards,
Bruce
