Hi,
normaly Testa must ignite, because everything
needed is doubled in that car. but you should
check the fuel-pump cables on the circuit board
in the front of the car; they scorch by years
and so the pumps do not have power anymore.
then you should check the relais for the fuel
pumps on the circuit board - there are to of
them; maybe they do not switch anymore. if this
does not help, then check the blackbox in the
back of the car - on the right hand you will
find it beside the black boxes of the bosch-
system with to thick cables going in. inside
this box there is a big silver relais, too.
pull it off and then plug a cable in between
pin 31 and 87 - if engine ingnites, then this
relais is defect. |

You have to identify where the problem is
1st: qualify the motor, does it have compression and is the timing ( timing belt ) correct?
2nd: does it have spark...remember each side of the engine has a separate ignition system
3rd: does it have fuel...you might hear the pumps run but is fuel getting thru the filter to the fuel distributor?
Every gasoline engine requires the same approach.

If neither side of the engine runs it must be something common to both sides.
check ALL the fuses with a test light. make sure you have power on both sides...then pull back rug and check the wires coming out of the fuse block...my 87 TR had a good fuse but a bad wire off the fuse block and one fuel pump would not run... |

Marcus, I just have my car back from the shop. It had similar symptoms except in my case, only one bank was in trouble. The issue, a couple of diodes burned inside the Ignition ECU (located under the driver's side rear fender). Swapping the coils should not be a problem, and it seems to be standard procedure when diagnosticating problems like this. I figured this was the problem myself, but since this is an expensive component, I wanted a second opinion. It turns out that after parts were ordered, my mechanic was able to fix the ECU, hence we were able to cancel shipment of the parts.
Anyway, it seems that poor connectivity at the Fuse box can cause the Ignition ECU to go bad. Unfortunately, this seems to be a common issue with TRs.
I tried checking several other items as well. You might want to search for the "TR dies during warm-up" discussion, to get other ideas of what to check.
Good luck! |

My 85 Euro Testarossa doesn't ignite properly when I try to start the car. The starter motor runs and the engine starts cranking, but it never fires up. I do hear it fire up for a fraction of a second, and then die again.
A similar problem occured last month. At that time I disconnected all the connections to the circuit board up front and plugged them back in (making sure the connections were good), and it started on the next try. No such luck this time -all the connection seem fine and solid (pulled every one).
I swapped the left and right ignite coils - no luck. Also sprayed "starter gas" into the air intake - noticed no firing. I hear the fuel pumps run when I turn on the ignition.
Suggestions? The fact that cleaning the connections upfront last time solved an identical problem, indicates that it is likely an electrical problem.
Also, when I swapped the igition coils I might have swapped the ground and the voltage cable powering the coils. Could this damage it? Didn't see any markings, which connector is the ground? Where is the ignition module? Is that under the connector on the same platform as the coil?
Thanks,
Marcus |
