Parked since 2004 ,had rusty tank issues,replaced tank and cleaned lines,new bosch pumps ,filter ,have spark and good reading on alternator output,fuel pressure good and checked little filter coming into the FD ,the fuel lines to the motor are not getting fuel when checked on initial startup.I have an 85 cossie sitting beside it that had pretty much the same scenerio as it was also a parker but is now running .I borrowed the FPR from the 85 and put it on the 87 with some success ,would start w/ some coaxing AFTER I plunged the plate underneath the air cleaner ,it then kept running and the motor sounded very good,all the readings on the motor from the gauges were at spec but I had to keep it above 1000rpms or it would stall out so no idle was ever realized.Its know back to a no start issue and it may be time to look closer at the FPR for replacement but would rather get a view from others past experience in the fueling department of these notoriously costly parts .A further report into swapped parts from the running 85 cossie was the Fuel distrubutor ,Its getting closer but its still not right .The one thing thats come up during some other read ups Ive glossed over on this subject is at the fuel tank ,an inline part on one of the return lines has a piece ,not sure of its name but could this be partially clogged and causing these symptoms ?

Its running again but not perfect yet,it seems to have a fuel pressure issue ,the accumilator seems to be a likley candidate.Can some one chim in and give testimony on their run ins with a fuel accumilator issue.I checked the resistance on the temp sensor and it looks in specs ,the fuel pressure regulator and iacv are suspects but will deal with them later.

What kinds of compression readings are you getting from each cylinder?

The "plate underneath the air cleaner" is the air flow sensor. It deflects with increasing air flow, and thru a link, moves the metering plunger in the fuel distributor (FD). When you pushed the plate down during starting, you increased the fuel flow from the FD. After sitting for 11 years some of the small fuel passages in the FD may be partially blocked by dried fuel residue. Since you have another operating engine at hand, consider taking the complete air flow sensor/FD package from that engine and installing same on the current project engine. The reason? All known-good air/fuel metering parts remain together as a calibrated unit. While that is being done, you will be able to inspect all the idle air hoses and fittings, and the idle air valve for condition.

Re: fuel accumulator
The accumulator is located next to the fuel filter with a hard line on the pressure side, and a soft line on the leak side. To test for accumulator internal leakage, pinch off the soft line.

There's a filter that needs to be checked behind the input line of the fuel distributer.

So what's a cossie?

Shorthand for Sarah Cossie Parker; a close relative of Jessica.

I have done the FD switch over from the beginning ,this was what got the car started ,to report on start up difficulty it takes some coaxing from me plunging the metering plate a couple of times ,going back and turning the key over for 10 seconds with half a gas peddle to realize startup ,it then wont idle ,i keep it around 1200 rpms .The iacv looks orig but is different than my 1985 car ,strange. Ill clean it up and try this out next.

Jessica Who?

I missed that tip on the accumilator Frank about the soft line pinch off ,what will be the effect? Google find ,so if it starts quicker it might be the accumilator .In respect for those who teach ,thanks very much for your part ,a student these cars will make of you.The other parts of interest is the IACV ,can it be tested as well ?? A carb spray cleanup or no.

When the accumulator diaphragm leaks, system pressure does not rise to the design value because the leak returns fuel to the inlet side of the pump, instead of holding pressure. By pinching off the leak line a temporary check is made of that possible source of low system pressure.

Not only "Jessica who" but why is this even relative?

It is not relative, ergo, you have answered you own question!

Could be a relative

Some success ,cleaned the IACV very carefully without just dumping it into a can of cleaner and letting it soak, the piece showed plenty of internal gunk while cleaning .The fuel pressure regulator has been addressed along with a checkout of the accumilator ,cleaned injectors andchecked vac lines and secured any possible leakers for vac loss .The car fires up quicker AND RUNS GREAT ,but no secured idle .Im guessing someone in the past has messing with the lambda tower mixture set screw which I have no experience on ,Ive read plenty upon its importance of idle and its particular setup procedure but nothing more than that,time to buy some diagnostic tools.
